There's a difference between "provoke" and "belittle", though.

I don't think I would feel too bad about myself if I had to call a method starting with "i_suck_", but I can understand and sympathize with people for whom having to type in that method name would strike right at their impostor syndrome.

The question is, of course: should we cater to those latter people? The author of this Ruby code clearly thinks not (or didn't think about it at all). I think that we (or at least I) should.
