New submission from Eric Snow:
In issue #19713, it came up that while PEP 451 deprecated Loader.load_module(),
it did not provide a suitable replacement for calling it directly. We've
worked around this in the stdlib by making calls to private APIs, but that
won't work so well for the community at large.
The importlib._bootstrap._SpecMethods class is one we had considered making
public, but decided to defer that decision until people demonstrated an
interest/need.
At this point in the 3.4 release cycle I'm not sure how much we can do about
it. Adding something like the following would be easy, but then we'd be stuck
indefinitely with an API that we may just deprecate in 3.5 (a one-hit wonder),
though that might be the lesser evil.
def load_from_spec(spec):
_spec = importlib._bootstrap._SpecMethods(spec)
return _spec.load()
Adding that as a recipe to the load_module() docs wouldn't work too well
either, since we'd still be advocating the use of a private API as a workaround.
To be honest, I'll have to defer to Brett, Nick, et al. on this one. They have
the experience to know the best approach to take here. I just haven't been in
the majors long enough.
(Where'd Guido put the keys to that time machine?)
