Comment (by simonpj):

 There are two things going on here

 * Allowing uppper-case names for overloaded labels.  This sounds plausible
 to me, although I have not thought through the consequences.

 * Some form of overloading for pattern matching, building on pattern
 synonyms.  Certainly sounds interesting, but should really have its own
 ticket and wiki page.
