//   Add Tests for:

//     on anonymous fields, _struct (all fields), etc
//   - codecgen of struct containing channels.
//
//  Add negative tests for failure conditions:
//   - bad input with large array length prefix
//
// decode.go
// - UnreadByte: only 2 states (z.ls = 2 and z.ls = 1) (0 --> 2 --> 1)
// - track: z.trb: track, stop track, check
// - PreferArrayOverSlice??? (standalone test)
// - InterfaceReset (standalone test)
// - (chan byte) to decode []byte (with mapbyslice track)
// - decode slice of len 6, 16 into slice of (len 4, cap 8) and (len ) with maxinitlen=6, 8, 16
// - DeleteOnNilMapValue (standalone test)
// - decnaked: n.l == nil
// - ensureDecodeable (try to decode into a non-decodeable thing e.g. a nil interface{},
//
// encode.go
// - nil and 0-len slices and maps for non-fastpath things
