Well, I haven't really used ADos pattern matching much -- my only real example
was taken from an incorrect example provided in my 2.0? Workbench which
tended to crash my machine every so often :)
However, wouldn't such uses usually be enclosed in parenthesis?  ala foo.(h|c)

That might make the parsing a bit simpler.  At worst case you'll need to put
some white space in there...  Having another non-standard symbol would push
the readability of this news group way down (due to tonnage of abusive flames).

While we're at it, why not make those ">" and "<" placable anywhere on the
command line?  [IE.  figure out how "run" would redirect output correctly...]
