+Aliasing Decorators
+-------------------
+
+When writing a library with a couple of decorator factories 
+(i.e. functions returning decorators, like ``complex_decorator`` from the
+:ref:`annotating-decorators` section) it may be tempting to create a shortcut 
+for a decorator. 
+
+Different type checkers handle :data:`TypeAlias <typing.TypeAlias>` involving
+:class:`Callable <collections.abc.Callable>` in a
+different manner, so the most portable and easy way to create a shortcut 
+is to define a callable :class:`Protocol <typing.Protocol>` as described in the
+:ref:`callback-protocols` section of the Typing Specification.
+
+There is already a :class:`Protocol <typing.Protocol>` called
+``IdentityFunction`` defined in
+`_typeshed <https://github.com/python/typeshed/blob/main/stdlib/_typeshed/README.md>`_:
+
+.. code:: python
+   
+   from typing import TYPE_CHECKING
+
+   if TYPE_CHECKING:
+       from _typeshed import IdentityFunction
+
+   def decorator_factory(*, mode: str) -> "IdentityFunction":
+      """
+       Decorator factory is invoked with arguments like this:
+         @decorator_factory(mode="easy")
+         def my_function(): ...
+      """
+        ...
+
+For non-trivial decorators with custom logic, it is still possible 
+to define a custom protocol using :class:`ParamSpec <typing.ParamSpec>`
+and :data:`Concatenate <typing.Concatenate>` mechanisms:
+
+.. code:: python
+
+   class Client: ...
+   
+   P = ParamSpec("P")
+   R = TypeVar("R")
+  
+   class PClientInjector(Protocol):
+       def __call__(self, _: Callable[Concatenate[Client, P], R], /) -> Callable[P, R]:

+   def inject_client(service: str) -> PClientInjector:
+      """
+       Decorator factory is invoked with arguments like this:
