I really like pattern matching in Rust, but I find myself using it less and less. `if let` and `let ... else` require substantially less indentation, and I often use them for Option values. I don't miss this syntactic sugar in OCaml though. Maybe it's just because OCaml has a 2 space indent, unlike Rust's 4 space indent?

Bril is a cute intermediate language for teaching (think simplified LLVM IR): https://www.cs.cornell.edu/~asampson/blog/bril.html The idea of providing a standard JSON format to help students write basic passes is really elegant.

I've been experimenting with an 'evaluate up to cursor' mode for my PL project. I love evaluating self-contained snippets in Lisp, this generalises the idea. The interpreter remembers the arguments when you run tests, then can re-use them when you say 'eval up to here'. What do you think?
