Okay.  My only concern is that I'd like to keep the ability to use
non-standard characters in names.  I don't mind if you change the
notation for this though.

The reason I want this feature is because I automatically generate
Mercury code from another language that allows non-standard characters
(such as "-") in names and I'd like to avoid having to mangle the names
in the generated Mercury code.

Ian.
