This has been open since april, and becomes immediately
relevant with rhettingers dict.fromseq() classmethod
addition: patch #643443. I hadn't seen this bug report
before, but looking at Raymond's code I wondered why cls was
passed as part of args instead of as the first arg of the C
function. I ended up here... I think it's *crucial* this is
fixed before the first alpha of 2.3 is released. Upping the
priority by one...
