.parse fails for new ES6 comprehension syntax
js> [for (a of [1,2]) a] [1, 2] js> Reflect.parse('[for (a of [1,2]) a]') typein:4:0 InternalError: bad parse node
Hm, so Reflect.parse is specific to the old spidermonkey syntax that is incompatible with the new comprehension syntax. What would be the best way to coordinate such a breaking change?
Summary: Reflect.parse fails for array comprehension → Reflect.parse fails for new ES6 comprehension syntax
Reflect.parse is now used by browser_parsable_script.js, that means everytime someone pushes a patch using comprehensions the tree gets orange. Mano just hit this on fx-team. That's quite saddening.
Comment 2 sounds like we're heading for an orangefest on TBPL. That sounds bad :) Jason, any ideas for a path forward here?
This is ridiculous. Something like this should be enough for disabling browser_parsable_script.js for the time being with no questions asked.
Bug 1065450 has some more details, so duplicating this in that direction.

the only problem is whether that bug will workaround lack of support for comprehensions in reflect.jsm somewhere else. in such a case this bug would still be useful to fix reflect.jsm.

It will, as far as I can tell from the discussion there (bug 1065450 comment 2). Note: I've moved the needinfo request as well.
