No, because "x <-- y" is already legal syntax
You could handle that by making the grammar more complicated.
Or just have the tokeniser treat "<--" as a single token, the
same way that it treats "<=" as a single token rather than
"<" followed by "=". It would be a backwards-incompatible
change (if you really wanted "less than minus minus something"
you'd have to put a space in somewhere) but replacing the
assignment operator is already a much bigger one.
