Shit hot, yes yes yes!!
Need to wrap my head around this: "A runtime bug is now a compile time bug."

This feels related to some new type-ish stuff I've seen where strings (like URI structures) are being type defined and checked, and noted to myself I needed to know how to do this.  Seems like this might be how.

Sounds like something useful for a dependency injection

I have mixed feelings about branded types after using them for a year.

The added type safety at compile-time is fantastic, but you have to manually cast every single one with `as`, especially when parsing strings from URLs or working with APIs.
