That's true. Another thing keywords provide are "anchors" that enable
better error recovery.
Read Herb's article; he mentions error recovery. I agree that the ";" at
the end of the line is a useful anchor, but in the position "in" "out"
and "body" can appear, the ONLY valid words are in, out, body, const,
immutable, shared, pure, nothrow, etc. So the error messages for these
ones won't get much worse.
For category 3 (keywords that can appear where identifiers can), I agree
it could get confusing. But at least category 1 (keywords that cannot
appear in the same place as identifiers) would be little loss.
