I just want to throw a plug for the concept of Railway Oriented Programming. It can be laid on top of almost any functional-ish language that can implement some sort of Result(Ok,Err) return type. And to the OP's point, you can catch exceptions where they occur and `return Result(Err(details))`. We applied ROP with great success at a fintech where we wanted to clean up a block of business logic with many failure paths. Instead of a forest of nested conditionals or try/catch mess, there was a very simple happy path with clear handling for all the errors. Here's a good start. Ignore the language details, the concept is universal. https://fsharpforfunandprofit.com/rop/ https://fsharpforfunandprofit.com/rop/
