By the way, it should be possible to handle regular expressions in an 
Haskell-like way.  I always couldn't understand why one has to write regular 
expressions as strings which have to be interpreted at runtime.  I would 
prefer something like this:

	identifierRegExp = alpha +++ iterate (alpha ||| digit ||| underscore)
	alpha = ('A' `to` 'Z') ||| ('a' `to` 'z')
	digit = '0' `to` '9'
	underscore = only '_'

What do others think?

Best wishes,
