Could we also do some multi-dispatch here or typechecking of $P2
so that it could also be a whitespace-separated string of subnames
to import? Then instead of
$P2 = split ' ', 'foo bar baz'
$P0.'import'($P1, ['ImportedNameSpace'], $P2)
we could write
$P0.'import'($P1, ['KeyTo'; 'ImportedNamespace'], 'foo bar baz')
It also helps in the case where we only want to import a single
symbol.

I believe there was a way to do this (using interpinfo), and
I agree that it would be much better. And perhaps it could then
be an optional named parameter, so that we import into the
caller's namespace by default, but there's an option to
import to another explicit namespace.
