I doubt it will gain champions. Once you have try/catch/finally, you've
got enough to build such things via libraries. Adding channels under the
hood doesn't help hide StopIteration, since control flow must stop and
unwind when it is thrown. We can't blast past default-channel
try/catch/finally's seeking one that handles StopIteration, we must at
least run the finally clauses.
Yes, that was how I meant it. And every channel's finallies, not just
the default one.
But those finally clauses if written for ES3 or above will assume that
any abrupt completion was a default-channel exception, i.e, that the
catch clause ran. Your proposal as I understand it breaks that
compatibility constraint.
Hm.
Good point, did not think of this.
