Yes, but as you know, correlation is not causality.  I'd say the
pleisomorph you're looking at originates with the description of
Abstract Data Types (ADTs) -- which are one of the the most mis-taught
topics in introductory computer science -- and the work on ADTs is the
ancestral work of the instances you're looking at.
