If you forbid redefining keywords, you remove the whole point of this
proposal: to allow keywords to be sometimes used as bona fide keywords,
sometimes as identifiers.
I really do not intend to give offence (I know that that's
counter-productive). But I have formed a very strong opinion - which of
course may be wrong, and certainly won't be universally shared - and I
am honestly expressing that opinion: Nothing I have seen in this thread
so far has persuaded me that this proposal has any merit.
