Because it's odd to have these "plumbing" methods in the same namespace
as the "porcelain" methods (the ones that implement the exposed
functionality of the class.)

The desire to keep this separation of namespaces is one of the reasons I
understand Phillip is championing `defop`, though other approaches would
for example include explicit method namespaces.
