Are you saying that there is a problem with isstring? Or proposing a
slightly different formulation?

If the latter: does UserString really behave enough like a string to
"work"? I've never tried it. In particular, does passing a UserString to a
regexp do what you expect? Can you pass a UserString to the open() command
as a filename, etc.?
