The .transform() methods would simply check for the corresponding

str.encode() would check for (str, bytes), bytes.decode() for
(bytes, str).
Alternatively, we could just not check the type combinations
at all and only apply the result type check.
Note also that both bytearray and bytes provide decode() methods, and
will presumably provide transform() methods, so actual type
annotations may not be the best way to go about this.
I'm not sure I understand.
If we went with the approach of checking type annotations on the codec,
then would a codec which was only annotated with (bytes, str) on the
decode method be usable by bytearray.decode()?
And if we aren't going to check the type annotations before invoking the
codec, what's the point in having them at all? Better to leave them out
entirely, invoke the relevant method of the named codec and see if we
get the right type back.
Cheers,
Nick.
