I didn't mention it, but I do write architecture diagrams which have input. data Version = Current | Future generate :: Version -> Diagram Implementation uses a few if/else expressions. Really simple. The final points of the post was that we should be able to generate architecture diagrams from other code. Parsing a service descriptor, generating them from tests, etc. You DO need a programming language.
