>The command shell may want to look for this flag as an instruction as to how the source it reads in should be interpreted - to create SourceCode/SourceProvider objects with an ES6 flag set (perhaps this should be a new default-to-false argument to makeSource).

This can make sense, yes.

> I don't know what you'd do with a harmonyBlockScoping global setting - for ES5 scripts it only makes sense to not use harmony scoping rules, for ES6 scripts it only makes sense to do so.

Block scoping is actually a compatible change, as far as strict-mode ES5 goes, so it can make sense to say "ES5 strict-mode also has the compatible parts of ES6" -- the "compatible extended mode" I mentioned in https://lists.webkit.org/pipermail/webkit-dev/2011-December/018903.html.

> I'd suggest that this is a small enough change that it may be wiser to introduce this alongside the first actual harmony feature implemented.

Fair enough.

Thanks for the review :)
