This makes for wtfjs additions, but they all seem non-wtf on

yield is reserved only in function* can work them out.
The star after function really helps. ES5's "use strict" directive
prologue in the body applying to its left (even in ES5 --
duplicate formals are a strict error) is goofy.
Agree on all counts, but not quite understanding yet.
Say I'm parsing this, and the token stream is paused at the "#":
function(a = # yield
I assume that we're not un-reserving yield in strict mode. That means
that I don't know whether to treat `yield` as an identifier or
reserved word until I get to that goofy prologue.
Ouch, you're right. We can't handle this without backtracking. Waldemar
should weigh in.
