More importantly, the competing PEPs have different champions, so you
and Larry need to be free to make the best case you can.


P.S. I was thinking the last time we had truly competing PEPs was way
back when the with statement was designed, but it turns out the
competing namespace package designs were also separate PEPs. PEP 315
was more an after the fact here's-a-better-way-to-implement-this
redesign of PEP 309, and PEP 3150 vs 403 is just me having an ongoing
discussion with myself (and occasionally others) over a feature I
doubt would ever make it past Guido even if I do eventually decide to
propose one of them.
