What if the policy class provided the behavior you would otherwise control with a conditional? For those policies in which the behavior is not needed, the inline, static member function would do nothing. For those in which the behavior is needed, the member function would do the work unconditionally. Changing the policy changes the behavior, so no need for a conditional.
