Not in the strawman. Without a leading special character, that's a bridge too far.

Even now the ambiguity with comma expression requires a cover-grammar parsing hack, which is used for destructuring assignment and even (going back to ES1) left-hand side of assignment. This hack is done for assignments, doable for destructuring (SpiderMonkey and Rhino do it), and controversial for arrow function formal parameter vs. comma expression parsing.
