So no need to target a very specific version of Python.
Yep, this is what I had in mind. And it appeared too trivial to place
it in the PEP.
Trivial and wrong.
Since thing and __preview__.thing may have subtle, or major, API differences,
how do you use it?
try:
result = thing.foo(a, b, c) + thing.bar(x)
except AttributeError:
# Must be the preview version
result = thing.foobar(a, c, b, x)
