Discussion aside, I notice with pleasant surprise gcc has an introspection primitive we didn't think of: __is_constant that (I assume) yields true if the given expression has no side effects.
In D the primitive would be called e.g. __has_side_effects to avoid confusion with the "const" qualifier.
I wonder how difficult it would be to define __has_side_effects (it would apply to an alias) and how it can be put to good use.
