-// Package mapstructure exposes functionality to convert an arbitrary
-// map[string]interface{} into a native Go structure.
-//
-// The Go structure can be arbitrarily complex, containing slices,
-// other structs, etc. and the decoder will properly decode nested
-// maps and so on into the proper structures in the native Go struct.
-// See the examples to see what the decoder is capable of.

-// The type should be DecodeHookFuncType or DecodeHookFuncKind.
-// Either is accepted. Types are a superset of Kinds (Types can return
-// Kinds) and are generally a richer thing to use, but Kinds are simpler
-// if you only need those.
-//
-// The reason DecodeHookFunc is multi-typed is for backwards compatibility:
-// we started with Kinds and then realized Types were the better solution,
-// but have a promise to not break backwards compat so we now support
-// both.

-	//     FALSE, false, False. Anything else is an error)
-	//   - empty array = empty map and vice versa
-	//   - negative numbers to overflowed uint values (base 10)
-	//   - slice of maps to a merged map
-	//   - single values are converted to slices if required. Each
