Allow for user specified key/values in marks?

[goodboy]

Pertaining to the original request in #133 does it make sense to allow users to pass in custom key/val pairs to marks (via **kwargs or some other API) such that user defined collection and/or hook calling behaviour can be controlled/modified by the user based on their own inputs (maybe it's more relatable in the context of #151).

It would potentially look something like:

from pluggy import HookspecMarker

hookspec = HookspecMarker('blah')

@hookspec(historic=True, a_special_hook=True)
def my_special_hook(arg):
    """This hook is only collected in special cases."""
    pass

lets wait for a real problem that needs this

i'd like to adopt a c4.2-ish approach where we only fix things that has a direct real world impact - abstract feature requests rarely yield a usable api in th first iteration

@RonnyPfannschmidt agreed just thought I'd log it for future reference/discussion.

i think we can close this one
