As it happens, I’ve been thinking about a library I’d like to develop in F# as an exercise to learn the language.
I have a hand-rolled proxying inference framework written in Python that is similar in purpose to something like LangChain but much more stripped down, less abstraction. Similarly to many other Python tools, it leverages the reflective capabilities of the language to do things like ask LLMs for responses conforming to a data class, or pass native Python functions as tools. Best of all, it relies on native Python constructs like docstrings to provide additional context to the inference APIs, making clean and well documented code a secondary programming model in a sense.
Perhaps it’s vanity, but at least in Python I find the resulting code quite elegant. I became curious what it would be like to port this to other languages, and surprisingly found that F# would, to my eyes, end up with the most lovely analogue.
Even languages I expected to be expressive and terse, like Haskell, couldn’t express the same ideas as understandably yet concisely as F#.
