That one (that I've used) must work, with the simple lookahead I've put in the lexical grammar, in order to continue to parse `x?.3:0` as today. > ?[] > ?() For those it is difficult for the parser to easily (i.e. quickly, without trying and backtracking code of arbitrary length) distinguish from the conditional operator, as in: `x ?(y - 2) + 3 : 0` Also, the difference of precedence level between the two operators makes the use of a cover grammar (I think) impossible. > ?: I'm not sure what that one should be used for. (If you mean the Elvis operator, it's out of the scope of the proposal.) —Claude _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
