> Oh, also, if y'all are fine with binding to Rust (through a C ABI) I'd love to help y'all use unicode-segmentation, which is much less work that pulling in ICU. Otherwise if y'all have implementation questions I can answer them. This spec is kinda tricky to implement efficiently, but it's not super hard.

Is the idea here that we'd take on a new dependency on the compiled `unicode-segmentation` binary, rather than adding Rust into our build system? Does `unicode-segmentation` support all platforms that CPython supports? I was under the impression that Rust requires llvm and llvm doesn't necessarily have the same support matrix as CPython (I'd love to be corrected if I'm wrong on this).

(Note: I don't actually know what the process is for taking on new dependencies like this, just trying to point at one possible stumbling block.)
