Another nice to have: make # less ambiguous

On my wishlist is forbidding the use of # just about anywhere but as a 
comment starter and in strings or regular expressions. Not a big deal, 
but it would make it easier to write 90% correct perl syntax parsers. 
It's a pain dealing with q#not a comment# and m#still not# and 
s(even)#this#. Especially since $# is going away (or did I make that up?).
