This is an explorative study of the application of the monistic Actor Network Theory (ANT) as a metaphysics, in a field predating with a tendency of excluding the human actant from the equation of programming language theory. Also it is the application in itself, upon a case of searching for the human-bound forces that drive the developement of a subset of programming languages. As a theoretical basis, the interpretation of ANT as a metaphysics by Graham Harman is chosen. Based upon his interpretation, discussions upon some specific aspects emerged concerning the interpretation of ANT as a metaphysics. The family of languages chosen for study is of the statically typed functional language type. This is partly based upon the narrators own experience with this family of languages. This has been an influential factor in the case study, caused by a method of including the narrator as an interpreting actant.
