I just upgraded to ST4...
the snippets for Python lang are now annoying because of the way they trigger while typing
e.g. attempting to type a class def like:
what happens is that as soon as I type the colon after WTF, the autocomplete pops up, and then hitting enter selects the first option.
So the code I end up with is:
…with my cursor positioned after the t in “init”

I believe these come from SublimeCodeIntel as disabling the package stops this snippets autocomplete from popping up, and I don't have any other Python-lang-specific packages installed (and apparently they are not coming from ST4 itself)
