I notice that "globals" is on the "you won't use this much" pile. I am wondering, when using Python interactively from Emacs, I often do this kind of thing:
if 'myvar' not in globals():
myvar = ...
That way I can just execute the whole buffer instead of having to carefully be picky-choosy about what I send to the interpreter. It's especially helpful if the line involves loading a large file, calculating something that takes a while, or downloading something. Is there a better way to handle this in an interactive context? Like an automatic globals cache of some kind?
