for the same effec:
let i = 42, j = 3;
for (let x in (i *= j ,{}));
So? I wrote "effect" not "scope", now you're defending the unwanted
degree of side-effecting freedom? :-|.
One can always make expressions have effects. That's not the point. The
reuse of VariableDeclarationNoIn in 12.6.4 without any refactoring or
semantic restriction to forbid an initialiser was a mistake. I'm glad to
get rid of it, but teasing me will cause endless grumpy fear that it
will live on. :-P
