Rigorous input parsing

[abiggerhammer]

I'd love to do a chapter on input handling with formal parsers. I've written a C library (with bindings for lots of other languages) intended for exactly this purpose, and am in the process of editing a series of video tutorials for implementing JSON-RPC with composed parsers. This would be very easy to turn into a chapter.

Hi @abiggerhammer -- sorry for the delay on this. :(

I like what you're proposing, especially if composition was part of the conversation. Feel free to open a PR with early versions of what you're thinking about, or to ask more questions here.
