Request: Phab Differentials should include road maps

2014-10-14 Thread Richard Eisenberg
Hi devs, I have what I hope is a simple request: that patch submissions contain a road map describing the patch. I'll illustrate via example: I just took a quick look at D323, about updating the design of Uniques. Although this patch was fairly straightforward, I would have been helped by a

RE: Request: Phab Differentials should include road maps

Hello, Would it be better to organize proposals under one namespace? Right now they belongs to root namespace, so title index ( https://ghc.haskell.org/trac/ghc/wiki/TitleIndex ) is hard to use. I was going to start new page describing language extension, but I don't want do increase entropy
