Vim won't load due to an old path reference to 3.4 which was replaced in the python3 upgrade with 3.5
Uninstalling and reinstalling vim fixes the problem:

$brew install vim --with-lua --with-python3 --with-client-server --override-system-vi --with-tcl

Possibly related to use of absolute path here?

This is expected; the rebuild is necessary. Thanks for reporting!

[remy-actual]

No problem.
Would it make sense to add a warning?
Either to python3 formula Caveats, or to the bindings section of the referenced documentation?
Running $brew upgrade and then having to stop and fix a broken code editor = not fun morning 😐

[tdsmith]

I know, sorry. We pushed http://blog.tim-smith.us/2015/08/python-35-transition/ out to the mailing list and Twitter. I hadn't considered the caveats of the python3 formula but I think that's a reasonable place to give advice. (Though I think most people ignore them!) Tim Sent from mobile

Ha, no apology necessary!
Can't speak for anyone else, but caveats are my starting point for troubleshooting anything Homebrew related.
Just sent a signup email to homebrew@librelist.com for the mailing list. Thanks for the reply and the tip 😄

@tdsmith I think it's worth revisioning all the relevant formulae. Unfortunately I think this roll-out has shown that a blog post on Twitter and the mailing list isn't enough to reach our users and I think this rollout was a bit premature, honestly.

[tdsmith]

We were never going to hit awareness saturation and it's a breaking change for tools outside of Homebrew no matter when we pull the trigger. I wish I'd remembered that compiling numpy was broken but at least there are okay workarounds.

There are fewer formulas with optional :python3 dependencies than I'd imagined. In core, they are boost-python, hashpump, macvim, nghttp2, notmuch, pygobject3, pyqt, pyside, qscintilla2, shiboken, sip, uwsgi, and vim. Shall we revision them?

Yeh, I reckon that's probably worth doing. Probably better to force an unnecessary rebuild than avoid a necessary one 👍
