RFC: What should ?foo do?

I haven't done it, but I suspect we could introduce special behaviour 
for ??foo very easily.  We could even have a whole hierarchy:

?foo, ??foo, ???foo, ????foo, ...

  

Heh, that's rather nice, actually. In words, that could read

?foo: tell me about foo!
??foo: what can you tell me about foo?
???foo: what can you tell me about things like foo?
????foo: I don't know what I'm looking for but it might be something
related foo?

You do have to be careful about messing with ?, though. I think many
people, including me, would pretty quickly go nuts if ?par suddenly
didn't work the way we're used to.
