I consider myself a fairly experienced Python coder and although I am not "uncomfortable" with significant whitespace there are a few places where I do find it annoying and I wouldnt mind an alternate block delimitation syntax. I would prefer something like the ruby "end" though rather than '{' and '}'. The place I find it annoying is in pasting snippets of code from say web pages. I very often google for a piece of code and then paste it into my editor and almost always the pasted piece of code has different indentation and causes a compiler error. Sometimes in vim "100==" fixes it but very often not. It would be nice if you could use an "end" delimiter for quick experimentation with code and then later on go and remove the "end" and fix the indentation.
