The brain_typing module does not add a ABCMeta_typing class thus there is no need to test it.

* Solves "Duplicates found in MROs" false positives. (#905, #916)Marc Mueller2021-02-281-0/+115
| | | | | | | * Adds inference support for all typing types that are defined through _alias function * Instead of creating a new class (by the mean of TYPING_TYPE_TEMPLATE) infer the origin class : i.e MutableSet = _alias(collections.MutableSet ...) origin is the class in collections module. Needs to add __getitem method on its metaclass so that is support indexing (MutableSet[T]). * Enable _alias mocking and testing only if python version is at least 3.7 Co-authored-by: hippo91 <guillaume.peillex@gmail.com>
