Fixes #113
This PR does two things:
await
is not used in anasync
functionasync
as anIdentifier
when source type is module (as outlined in Fix reserved keywords #134). See http://www.ecma-international.org/ecma-262/6.0/#sec-future-reserved-words for relevant part of the spec.Marking this as WIP because I haven't been able to figure out how to warn for
await
outside of functions safely. Please see comment below.
