This is possible, but only when using eval'd code, which is generally frowned upon.

Given a class constant Permission::ACCESS_NONE e.g. you could do something like this in the yaml file:

eval("return \The\Complete\Namespace\To\Permission::".$context['permission'].";");

This is of course butt-ugly code but it does work.
