There already is an alias substitution rule for preventing these problems:
The first word of the replacement text is tested for aliases, but
a word that is identical to an alias being expanded is not expanded a
second time.
and I think that's enough; you can still produce reserved words and
have them recognized as such. There is no need for such radical
changes to the language.
