I doubt that Funciton, in its current form, could be useful in education. It doesn’t embody the most widely used programming paradigm (procedural) but instead is a declarative functional language, which makes any skills obtained by studying it pretty much untransferable. Secondly, its syntax does not allow for naming of variables and parameters (except perhaps through comments) which is an anti-pattern. If these could be addressed in a derivative concept that is actually designed for education, it could work. As it stands, however, it’s just a quirky esolang.
