If ``firstresult`` is ``True`` the 1:N hook call (N being the number of registered
hook implementation functions) will stop at I<=N when the I'th function
returns a non-``None`` result.
If ``historic`` is ``True`` calls to a hook will be memorized and replayed
on later registered plugins.

which will make it discoverable to :py:meth:`.PluginManager.register`.
If passed no function, returns a decorator which can be applied to a

If ``optionalhook`` is ``True`` a missing matching hook specification will not result
in an error (by default it is an error if no matching spec is found).
If ``tryfirst`` is ``True`` this hook implementation will run as early as possible
in the chain of N hook implementations for a specification.
If ``trylast`` is ``True`` this hook implementation will run as late as possible
in the chain of N hook implementations.
If ``hookwrapper`` is ``True`` the hook implementations needs to execute exactly
one ``yield``. The code before the ``yield`` is run early before any non-hookwrapper
function is run. The code after the ``yield`` is run after all non-hookwrapper
function have run. The ``yield`` receives a :py:class:`.callers._Result` object
representing the exception or result outcome of the inner calls (including other
hookwrapper calls).
If ``specname`` is provided, it will be used instead of the function name when
matching this hook implementation to a hook specification during registration.
