Really interesting article, have claps!, but somewhat daunting.

I've written a bunch of CLIs in Python using the excellent Typer library, and it was very little work to get very polished APIs based on an existing library (or in one case, based on brand-new code.)

Someone should package all that you have written together into one Rust crate that handles all the boilerplate and busywork!

Thanks for writing, good stuff.
