Typing of env.list is always list | None

[lucas-bremond]

Hi!

Is there any particular reason for the typing of env.list to be list | None even when providing a non-null default?

For example, the code below is valid:

my_list: list[int] | None = env.list(
    "MY_LIST",
    subcast=int,
    default=[],
)

but I believe we should expect my_list to be of type list[int] instead (that'd be consistent with the other types, e.g. env.int("MY_INT", default=123) returning int, etc).

Note that the same behavior is observed for env.dict as well.

Thanks!
