I *really* like the look of s:String (or String:s, which I used in my
quickie impl, they're interchangable), but I can easily see colons
being used for some other syntactic purpose down the road that we're
not yet aware of (ranges come to mind, eg. [0:50] as in python). And
of course, colons and other special characters are very helpful in
representing domain-specific semantics directly in code, so losing
those special characters is an expensive choice that should be weighed
very cautiously.
