But we *have* suggested banning mixed tabs and spaces
(rather than just recommending against it), which is
something that can be automatically verified.
I don't think this scenario is all that unlikely. A
program is initially written by a Russian programmer
who uses his own version of "a" as a variable name.
Later an English-speaking programmer makes some
changes, and uses an ascii "a". Now there are two
subtly different variables called "a" in different
parts of the program.
