Wow, that's a great guide!

I didn't read it in-depth yet, but I think I had a previous implementation that worked very similarly to theirs.

The problem with variable names is that they actually matter for some of the collaborative editor features I hope to implement in the future. There are certain assumptions I can't make quite yet, and so am keeping my options open :)

Have you thought about using type aliases or higher order types of some sort for that instead of relying on the variable name?

I could define that a familyname and a givenname are strings, and then a function argument of type familyname would be differentiated from a function argument of type givenname, but still the argument names themselves could be dropped from the hash.
