Looking at the grammar -- the only downside of the current approach
is that
you can't do 'await await fut'. I still think that it reads better with
parens. If we put 'await' to 'factor' terminal we would allow
await -fut # await (-fut)
Is there really a need to disallow that? It would take
a fairly bizarre API to make it meaningful in the first
place, but in any case, it's fairly clear what order
of operations is intended without the parens.
Greg, if grammar can prevent this kind of mistakes - it should.
I like my current approach.
