That's fine. My point was that the only optimizations possible are 
possible on strictly pure functions (the immutable cast one included). 
Weakly pure functions add nothing.

But merely having them around means that when I annotate a function with 
"pure", I do not promise any guarantees that the compiler can actually 
use to perform optimizations.
