G-J van Rooyen @gvrooyen.com · 20/01/2026My experience with agentic coding (Amp) and OCaml has been super positive - as in one-shotting an entire application that I now use daily. My working theory is that the strong type system gives the agent a very strict and tight feedback loop for converging on a working solution 272
