-// Package cmp determines equality of values.
-//
-// This package is intended to be a more powerful and safer alternative to
-// reflect.DeepEqual for comparing whether two values are semantically equal.
-//
-// The primary features of cmp are:
-//
-// • When the default behavior of equality does not suit the needs of the test,
-// custom equality functions can override the equality operation.
-// For example, an equality function may report floats as equal so long as they
-// are within some tolerance of each other.
-//
-// • Types that have an Equal method may use that method to determine equality.
-// This allows package authors to determine the equality operation for the types
-// that they define.
-//
-// • If no custom equality functions are used and no Equal method is defined,
-// equality is determined by recursively comparing the primitive kinds on both
-// values, much like reflect.DeepEqual. Unlike reflect.DeepEqual, unexported
-// fields are not compared by default; they result in panics unless suppressed
-// by using an Ignore option (see cmpopts.IgnoreUnexported) or explicitly compared
-// using the AllowUnexported option.

-// BUG(dsnet): Maps with keys containing NaN values cannot be properly compared due to
-// the reflection package's inability to retrieve such entries. Equal will panic
-// anytime it comes across a NaN key, but this behavior may change.
-//
-// See https://golang.org/issue/11104 for more details.

-var nothing = reflect.Value{}
-
-// Equal reports whether x and y are equal by recursively applying the
-// following rules in the given order to x and y and all of their sub-values:
-//
-// • If two values are not of the same type, then they are never equal
-// and the overall result is false.
-//
-// • Let S be the set of all Ignore, Transformer, and Comparer options that
-// remain after applying all path filters, value filters, and type filters.
-// If at least one Ignore exists in S, then the comparison is ignored.
-// If the number of Transformer and Comparer options in S is greater than one,
-// then Equal panics because it is ambiguous which option to use.
-// If S contains a single Transformer, then use that to transform the current
-// values and recursively call Equal on the output values.
-// If S contains a single Comparer, then use that to compare the current values.
-// Otherwise, evaluation proceeds to the next rule.
-//
-// • If the values have an Equal method of the form "(T) Equal(T) bool" or
-// "(T) Equal(I) bool" where T is assignable to I, then use the result of
-// x.Equal(y) even if x or y is nil.
-// Otherwise, no such method exists and evaluation proceeds to the next rule.
-//
-// • Lastly, try to compare x and y based on their basic kinds.
-// Simple kinds like booleans, integers, floats, complex numbers, strings, and
-// channels are compared using the equivalent of the == operator in Go.
-// Functions are only equal if they are both nil, otherwise they are unequal.
-// Pointers are equal if the underlying values they point to are also equal.
-// Interfaces are equal if their underlying concrete values are also equal.
-//
-// Structs are equal if all of their fields are equal. If a struct contains
-// unexported fields, Equal panics unless the AllowUnexported option is used or
-// an Ignore option (e.g., cmpopts.IgnoreUnexported) ignores that field.
-//
-// Arrays, slices, and maps are equal if they are both nil or both non-nil
-// with the same length and the elements at each index or key are equal.
-// Note that a non-nil empty slice and a nil slice are not equal.
-// To equate empty slices and maps, consider using cmpopts.EquateEmpty.
-// Map keys are equal according to the == operator.
-// To use custom comparisons for map keys, consider using cmpopts.SortMaps.

-
- // The algorithm below is a greedy, meet-in-the-middle algorithm for
- // computing sub-optimal edit-scripts between two lists.
- //
- // The algorithm is approximately as follows:
- // • Searching for differences switches back-and-forth between
- // a search that starts at the beginning (the top-left corner), and
- // a search that starts at the end (the bottom-right corner). The goal of
- // the search is connect with the search from the opposite corner.
- // • As we search, we build a path in a greedy manner, where the first
- // match seen is added to the path (this is sub-optimal, but provides a
- // decent result in practice). When matches are found, we try the next pair
- // of symbols in the lists and follow all matches as far as possible.
- // • When searching for matches, we search along a diagonal going through
- // through the "frontier" point. If no matches are found, we advance the
- // frontier towards the opposite corner.
- // • This algorithm terminates when either the X coordinates or the
- // Y coordinates of the forward and reverse frontier points ever intersect.
- //
- // This algorithm is correct even if searching only in the forward direction
- // or in the reverse direction. We do both because it is commonly observed
- // that two lists commonly differ because elements were added to the front
- // or end of the other list.
