-----------------------------------
    Resolution: Won't Fix

Every possible perfomance issue (that has not come from profiling) can't have a ticket or we'd have dozens of those.

> There are other places where we should use the UniquenessCache - QName objects - we really should arrange for comparing them to be a pointer comparison of an NS (now interned in the UniquenessCache) and a pointer comparison of an interned local name (aka a Symbol). 
> We do lots and lots of QName comparisons all over the place, both in the compiler and the runtime for both parser and unparser.
