Actually I would recommend against that -- I've had the pleasure of
writing a gas port (HPPA) where certain characters had different
meanings depending on their exact placement in a line. To this day
it still doesn't work 100% correctly -- the grammar is inherently
ambigious. In my case the character is a '!', and is used in
comparison operations, as a gas built-in operator *and* as a line
continuation character.
