Adding on to this, I think the point is that assignment bypasses the
usual *evaluation* rules, even though it is syntactically a binop.
I think it basically has to be so: For one thing, it is kind of
difficult to check for a signature match without evaluating the
arguments and the left hand side of an assignment will not in general
exist at that point.
