I agree, which is why I drew the line in paren-free about JS always being a curly-brace language. > Maybe the solution is a way to make return's expression non-optional? > If you want to return nothing, then you'd `return undefined` or > `return null`. Drag of a migration tax but it is an early error.

The haters are gonna hate when they really should look deeper. There is not a simple good vs. evil battle between using ; scrupulously or using ASI. If you assume ; is the one true way to terminate statements, then there's no debate at all. However, given the reality of ASI, in practice there are two ways to terminate statements. Then the question becomes, what is more usable, optionally turning off ASI, or under prior opt-in to Harmony, improving ASI? I think it's plausible that ASI can be improved, perhaps along lines you first suggested. E.g., return useless expression here; becomes an error in Harmony. Or we force return <expr>; and ban return; (but seems extreme to me at the moment). /be _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
