Boxer pioneered a model for computation, based on naive realism and its copy-on-execute mechanism, whose virtues were only slowly rediscovered in several different traditions over the following decades. These virtues went by various names in the different traditions (functional prototypes, first-class executions, non-divergence) and were embodied, in some cases unknowingly of Boxer’s example, in various systems such as Subtext, Flogo II, and Infusion. I believe this model has great implications for the experienced ergonomics of user programming, as well as connections with apparently unrelated traditions such as those of integration domains (Kell, 2009) and observable execution (Kell, 2012).
