The general fix would be to add
else: r += a[:0]
The awkwardness might be reducable if asciistr let
you write something like
r = asciistr('(', a)
meaning "give me either a string or bytes containing
the value '(', depending on the type of a".
But taking a step back, how bad would it really be
if an asciistr were returned in this case? Is it
just that asciistr doesn't behave exactly like a str
in all situations, so it might break something?
If so, would it help if asciistr were a built-in
type, so that other things could be made aware of
it?
