Not really. I would much rather see us not bother with this pedantic
syntax than introduce an even-partially-reserved word.
Having said that, I don't think I believe your analysis of why this
doesn't work. The presence or absence of commas ought to make the
syntax non-ambiguous, I would think. Maybe you just factored the
grammar wrong.
