It looks fine to me.  I'm still using Python 2.7 because I haven't found
a really compelling reason to migrate to Python 3, but this makes it
start looking worthwhile.

You could write some IDE features to suppress visibility of the hints.
Or maybe it could be done with a decorator-like construct:

  @-spec(Iterable[Real], Real) -> Real

I've always found Python 3 annoying because it broke compatibility with
Python 2, but only by a little bit, not enough to add real benefits.
This is a real benefit so IMHO it makes the language more attractive
rather than less.
