Yes, and that's exactly why it can be made to work
in this particular case. Most likely no testing for
callability is being done, only isinstance(repl, str).

This isn't so bad, because it's pretty rare for
someone to try to create a "string-like" object that
isn't a subclass of str. But callable objects can
be of any class, and such objects are frequently
used.
