I thought it was a consequence of the grammar, not the spelling of the
operator. The problem is due entirely to the fact that there is such a
thing in C as an expression that performs assignment, while C has no
such thing as an assignment statement - the closest it comes is an
expression-statement where the relevant expression is an assignment
expression. Those facts are completely independent of the spelling of
the assignment operator.

What alternative spelling for the assignment operator are you
suggesting, that could, without a change to any of the features of the
grammar that I described above, avoid this problem?
