I still don't understand this desire to delay semantic analysis, where are the examples of sema being a performance bottleneck? Just basic parsing already requires us to do a reasonable amount of analysis anyway, and while parsing shows up as being a problem, the bulk of that time seems to be lexing, and lexing is unavoidable even if all you want to do is syntactic analysis (unless we're proposing a delayed syntactic check mode?????)
You make good points. The counter-arguments were from Microsoft at the last TC39 meeting (two weeks ago). The followup from them (and from all implementors) was to provide more detail from profiling on where the costs lie. If they're mostly irreducible lexing, then you're right.
