Add wildcard variables #9

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Right now all variables must have names, even if we don't care about their 
values.  We should support underscore ("_") as a wildcard name, as in other 
functional languages.

I think these are straightforward, but let me ask about implementation
strategy in case anyone has a better/different idea:

* For wildcards: create (?) wildCardName that allocates a *fresh* Name
 that prints as "_".  Is this already provided by RepLib?

* For simple arrows: convert A -> B to (_:A) -> B.

I'll mark the issues as "started" if/when I actually start, so, if
anyone else is dieing to implement these, don't let me stop you.
