Is there a visual modeling language or style for the functional programming paradigm?

Question

UML is a standard aimed at the modeling of software which will be written in OO languages, and goes hand in hand with Java. Still, could it possibly be used to model softwar

Answer 1

I have watched a few video interviews, and read some interviews, with the likes of erik meijer and simon peyton-jones. It seems as when it comes to modelling and understanding ones problem domain, they use type signatures, especially function signatures.

Sequence diagrams (UML) could be related to the composition of functions. A static class diagram (UML) could be related to type signatures.
