// Fast path functions try to create a fast path encode or decode implementation
// for common maps and slices.
//
// We define the functions and register them in this single file
// so as not to pollute the encode.go and decode.go, and create a dependency in there.
// This file can be omitted without causing a build failure.
//
// The advantage of fast paths is:
//	  - Many calls bypass reflection altogether
//
// Currently support
//	  - slice of all builtin types (numeric, bool, string, []byte)
//    - maps of builtin types to builtin or interface{} type, EXCEPT FOR
//      keys of type uintptr, int8/16/32, uint16/32, float32/64, bool, interface{}
//      AND values of type type int8/16/32, uint16/32
// This should provide adequate "typical" implementations.
//
// Note that fast track decode functions must handle values for which an address cannot be obtained.
// For example:
//	 m2 := map[string]int{}
//	 p2 := []interface{}{m2}
//	 // decoding into p2 will bomb if fast track functions do not treat like unaddressable.
//
