I tend to agree, but I think a separate "clean-up" patch to do so is
more appropriate than rolling it into this fix.

I originally was of an opinion that we should take only lowercase
keyword followed by a colon, primarily because that is what we
produce. Then "the real world need" told us that we are better off
catching the keyword case-insensitively. Recalling that lesson, I
am not sure I would support "let's limit to the colon, rejecting any
other punctionation letter".
In any case, we should make such a policy decision outside a patch
like this one that is about fixing a behaviour which all users would
consider as a bug regardless of the policy they support.

I was primarily interested in catching negatives, and !n was a mere
optimization, but you are correct to point out that negative n at
this point in the codeflow is a BUG().
