Note that Python effectively has an open-brace (the colon) but no close-brace except for unindent. Personally, I hate this because if I'm in emacs and I hit the tab (autoindent) key the result may or may not be what I want. I personally use a programming style where I use a PASS statement as a close-brace so my code can always be safely autoindented without changing its semantics. But this is rather ugly. It would be better to have a less obnoxious but still backwards-compatible close-brace, like ## or maybe #> Some day I'll hack emacs-mode.elisp to support this.
