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.

Just for the fun of it, I implemented this as a template:
