Ah, so does the compiler figure out which ones are strongly and weakly
pure and then optimize as
appropriate? Is there a way to indicate that a function is strongly
pure? Because it would seem odd
to call a function you thought was pure and wind up with a mutated argument.
Just make sure all the parameters are either const or immutable or
passed by copy and do not contain any pointer or reference. That'll
make the function strongly pure, and the compiler will be able optimize.
