data-spec-validator's Issues

Dict will pass the LIST_OF check

class BroadcastSpec:
    recipient_tags = Checker(
        [LIST_OF], LIST_OF=INT)

not_ok_data = {
    "recipient_tags":{}
}
is_valid = validate_data_spec(not_ok_data, BroadcastSpec)  // returns True, but expected False

I can use [LIST, LIST_OF] to check if recipient_tags is a list,
but LIST_OF should check if recipient_tags is a list type IMAO.

[Feature Request] Support `Checker([LIST_OF], LIST_OF=Optional[...])`

Here is a minimum-reproducible code:

class _Spec:
    data = Checker([LIST_OF], LIST_OF=Optional[str])

validate_data_spec({'data': ['str', None]}, _Spec)
# TypeError: field: _Spec.data, reason: ['str', None] is not a spec of <class '__main__._Spec'>, detail: AttributeError('find')

tried with str | None

class _Spec:
    data = Checker([LIST_OF], LIST_OF=None | str)

validate_data_spec({'data': ['str', None]}, _Spec)
# TypeError: field: _Spec.data, reason: ['str', None] is not a spec of <class '__main__._Spec'>, detail: AttributeError("'types.UnionType' object has no attribute 'find'")
