+// 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.
+//
