I'm wondering if we should remove typing
from the stdlib. Now's the time to think about this, as the feature freeze for 3.7 is about 12 weeks away.
Cons:
typing_extensions
)typing
module was always provisional)Pros:
typing
module can evolve much faster outside the stdlibtyping_extensions
(and maybe even mypy_extensions
)If we don't do this I worry that we're entering a period where many new typesystem features end up in typing_extensions
and users will be confused about which items are in typing
and which in typing_extensions
(not to mention mypy_extensions
). Anything new to be added to typing (e.g. Const
, Final
, Literal
, or changing ABCs to Protocols) would have to be added to typing_extensions
instead, and users would be confused about which features exist in which module. Moving typing
out of the stdlib can make things potentially simpler, at the cost of an extra pip install
(but they'll need one anyway for mypy
).
Thoughts?
