------- Comment #12 from jeff at schwabcenter dot com 2009-05-19 18:07 ------- What he said. I'm perusing your patch, and I appreciate that you removed an artificial restriction. The right place to catch this is up front, in a concept check, rather than in _Destroy; since I'm not about to add the check myself, I'm hardly in a position to criticize. The diagnostic did have the nice property of catching a real, semantic error, though, and it seems a shame to let a known error go unreported.
