-:py:class:`List` provider is needed for injecting a list of dependencies. It handles
-positional argument injections the same way as :py:class:`Factory` provider:
-
-+ All providers (instances of :py:class:`Provider`) are called every time
-  when injection needs to be done.
-+ Providers could be injected "as is" (delegated), if it is defined explicitly. Check out
-  :ref:`factory_providers_delegation`.
-+ All other values are injected *"as is"*.
-+ Positional context arguments will be appended after :py:class:`List` positional injections.
