// The advantage of fast paths is:
// - Many calls bypass reflection altogether
// - Many calls bypass reflection altogether

// Currently support
// - slice of all builtin types,
// - map of all builtin types to string or interface value
// - symmetrical maps of all builtin types (e.g. str-str, uint8-uint8)
// - slice of all builtin types,
// - map of all builtin types to string or interface value

// 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.
// m2 := map[string]int{}
// p2 := []interface{}{m2}
