[Python-ideas] Indentation, again: Problems with moving and combining code across editors.

Besides, spaces become difficult to count and distinguish from tabs, adding to the problem. (Why allow tabs at all?)

Working code should not be broken gratuitously. Sure, it was an unfortunate decision in the first place, but we can't change that original decision now.

Why can't Python be made to accept the following indentation of code (in *addition* to the current schemes)?

Because we *already have it*: the character is ' '. If *you* follow that rule, you won't have problems copy/pasting your own code into well-behaved code. If you're working with somebody else's code which mixes tabs and spaces, *using an alternative character doesn't help*, whether the "bad" code is source or target.
