docs: Decorator applicable to functions, methods, properties,
      classes or modules (by explicit call).
      If applied on a module, memb must be a module or a module name contained in sys.modules.
      See pytypes.set_global_typechecked_decorator to apply this on all modules.
      Asserts compatibility of runtime argument and return values of all targeted functions
      and methods w.r.t. PEP 484-style type annotations of these functions and methods.
