Ikegami, I'm not sure what you're talking about. If you look at my original post, I did use my ($str) = @_;. I'm not avoiding the standard calling convention.

What would like from us?

Nothing. You answered my original question. (Thanks!) There doesn't seem to be any way around one of the two fixes I mentioned above and I don't like either of them (because they feel unnatural). I think the underlying problem is that $1 is a global and that interferes with the use of pass-by-reference.
