-1, "external" can be also understood as "exported" or public. I think that
the names in the updated proposal are the clearest. Also, I think that at
this point we need to stop trying to come up with more names. I don't think
that we will ever reach a point where everybody is happy with the names.
The ones that we have now seems to be a good compromise that is in line
with other Swift keywords.
