Hello #fsharp Twitter! Did learning F# or some other functional programming seem to “unlock” something for you? If you have a story or comment about how it changed your trajectory or outlook, I’d love to hear from you. Reply in the comments or send me a DM.

Part 2 - Using Cantor's unpairing function to map integers to our calculator language. (A recursive type) It's getting closer to being a total function. But what if we used unbounded bigints?

Generate: Int → Lang ???? Can we define a small recursive language and then map the set of integers to example instances of our language?

When two total functions (these should be uint, not int) map to each other in a special way, they can create a bijection. For this demo, we uniquely map the set of integers to a pair of integers and back.

F# is a pretty good at working with generics. If you see 'a or 'b or 'c (etc) in your function signature, it means you're defining a generic function. Maybe you did it on purpose, or maybe didn't give the F# compiler enough to infer the types you wanted.

Watching @shanselman video on @bletchleypark made me think - I have an hour on the train, let's port my own #fsharp Enigma emulator to @safe_stack! @FableCompiler is truly fantastic and makes this easy.

As soon as I saw @auchenberg's Browser Preview extension, I know I had to use it for an F# object printer for FSI based on @gmpl's original FsPad project. (github.com/gusty/FsPad/)
