Can getHash be made pure?

[H. S. Teoh]

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?
