You decide. Without that, the weak `pure` can still be used
inside strongly pure functions, but is otherwise useless for

If the function body is available and not too complicated,
probably. But with `pure` it's possible for a compiler to
optimise based on the signature alone.
I don't personally care that much about having a super-optimising
compiler, but I still wish that our attributes provide as much
info as possible for any analysis program.
