Meh.  Variable initialization is only one of multiple cases (assignment,
GET DIAGNOSTICS; maybe others, I've not examined the grammar).  Also,
if we do it like this, we're implying that both := and = are equally
preferred, which might not be the impression we want to leave.

I'd be a bit inclined to just stick a NOTE somewhere saying that "="
can be used in place of ":=" for assignment.
