Fwiw, Python talks about ["simple statements"](https://docs.python.org/2/reference/simple_stmts.html) in its documentation. So... it seems to be a thing, at least for grammar explanation purposes.

If we go ahead and make assignment a statement form, I guess this one becomes a statement form too.

Even here, lvalues get involved in a big way. Any side effect happening in the path of the lhs should happen _once_, which relates both to the Single Evaluation Rule...

Heh. The new implementation is [left-recursive](https://en.wikipedia.org/wiki/Left_recursion). Not a showstopper in itself, of course, but... interesting. * Easiest would be if the parser is able to take left-recursive things in stride....

That brings up another point. The "chaining operators" in Perl 6 (corresponding to all the comparison ops in 007) are "too diffy" to be assignmentopified. Perl 6 has a precedence...
