This is a copy of the first issue collected in #1206 to enable separate tracking of the bug.

The issue

Some of the inner validators accept lists while others still require the explicit use of and_. For consistency, I think all of them should ideally be able to handle lists. For the member_validator, the change has been in implemented in #925, but iterable_validator still struggles with lists. For example, the following piece of code works, but replacing any_ with a list will make it fail:

@define class A: x: List[str] = field( validator=deep_iterable( member_validator=[instance_of(str), min_len(1)], iterable_validator=and_(instance_of(list), min_len(1)), ), )

For deep_mapping, lists/tuples not supported for any of its three arguments.
