methods in order to to avoid AmbiguousMethods situations.This module
provides four decorators:
prioritized_when
prioritized_around
prioritized_before
prioritized_after
These behave like their peak.rules counterparts except that they accept
an optional prio argument which can be used to provide a comparable
object (usually an integer) that will be used to disambiguate situations
in which more than rule applies to the given arguments and no rule is
more specific than another. That is, situations in which an
peak.rules.AmbiguousMethods would have been raised.
This is useful for libraries which want to be extensible via generic
functions but want their users to easily override a method without
figuring out how to write a more specific rule or when it is not
feasible.
