--- Comment #5 from Marc Glisse <marc.glisse at normalesup dot org> 2011-11-29 10:27:18 UTC --- All right, now the is_abstract behavior is settled, do you think the fixed code provided by Daniel in comment #1 should produce a warning, since the declaration is absolutely useless (I may be missing something)? Or maybe there are legitimate meta-programming tricks I am not thinking of that would turn regular constructors into pseudo copy constructors to disable them?
