I've now looked at asciistr. (Thanks Glenn and Ethan for the link.)
Now that I (hopefully) understand it, I'm worried that a text
processing algorithm that uses asciistr might under hard-to-predict
circumstances (such as when the arguments contain nothing of interest
to the algorithm) might return an asciistr instance instead of a str
or bytes instance,
It seems to me that any algorithm with that property
has a genuine ambiguity as to what it should return
in that case. Arguably, returning an asciistr would
be the *right* thing to do, because that would allow
it to be used as a component of a larger algorithm
that was polymorphic with respect to text/bytes.
