I agree. The let declaration has to hoist, or else it isn't the new var, and then we'll have to throw out all those tee shirts. That's why I want a let block. (Actually, as I posted some time ago, I'd prefer to have the let block *instead* of the let declaration, but I realize that's a non-starter with most of the TC members.) _______________________________________________ Es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
