Re: python-mode (python.el): python-backspace

[Richard Stallman]

    There could be a python electric minor mode.

That would be a good way to handle it.

    Is any sort of "global electric" customization/variable that tells
    packages to turn on some default level of electricity?

No, and I don't see that it makes sense, given that these features are
ideosyncratic for specific modes.  If every major mode, or many of them,
had some sort of electric backspace, it would make sense to have
a uniform way to turn them on.  But they don't.
