This is not enough. What do you have to do if you want to be certain to have
distinct D functions pointers even if the function body may or may not be the
same? (There is C code out there that relies on this guaranteed, like some
evolutionary algorithm that breeds functions). Are D functions tagged with
extern(C) exempt from this optimization?
