local or global, too bad the phobos/druntime changes broke your

It's an issue, but I confess that I kind of gave up on local
imports working correctly when they refused to make UFCS work
with local imports (though IIRC, that was specifically Kenji and
not Walter - I don't know where Walter sits on it). I really
don't think that local imports should be any different from
imports at the module level except for the fact that they don't
affect stuff at outer scopes, but I gather that the
implementation doesn't jive well with that, and that's led to
refusals to make imports work the same at all levels when various
issues like this have come up.
That being said, D's module system does tend to have issues when
adding symbols to druntime, Phobos, or any library that someone
else might use. So, on some level, we're always going to have
this problem, but we can and should do better with that then we
do (e.g. making it so that private symbols never conflict with
anything when the module that they're in is imported).
