I'd like to think I'm not a moron, but when I stayed up until 6 am the previous night, I sure code like one sometimes. I'm sure most of the people on this mailing list have their moron moments, too.

Macho posturing about how only bad programmers need safety is not helpful. Real programmers *do* eat quiche.

(Actually, I think I have some mini-quiches in the freezer. I might go make some right now.)
