Still chugging away at implementing AA's in druntime proper, I reviewed the code for methods that can be marked pure but ran into a major road block: getHash() is not marked pure. That makes a lot of AA methods impure, that could, and probably should, be marked pure.

Is it possible to make TypeInfo.getHash() pure? AFAICT there's no good reason why it shouldn't be pure. Am I missing something?

It should be const, pure, nothrow, @safe.
