One problem I can think of is relying on the auto-inference can create fragile code. You make a change in one place without concentrating and suddenly a completely different part of your code breaks, because it's expecting pure, or @safe code and you have done something to prevent the inference. I don't know how much of a problem that could be, but its one I can think of. -- James Miller
