It's certainly *not* executed that way. The base class
expression is only evaluated once, when the class is
defined.

Are the XXX_Parent things used anywhere else? Maybe
they're being used for inherited method calls, and the
author wanted to insulate such calls from changes to
the base class in future versions.
