-Callable providers
-------------------
-
-``Callable`` provider is a provider that wraps particular callable with
-some injections. Every call of this provider returns result of call of initial
-callable.
-
-``Callable`` provider uses ``KwArg`` injections. ``KwArg`` injections are
-done by passing injectable values as keyword arguments during call time.
-
-Context keyword arguments have higher priority than ``KwArg`` injections.
