I'm pretty impressed with Cursor: I've successfully asked it to perform codebase transforms in English, and it's worked! E.g. "Replace all calls foo(..., true) with foo_immediate(...) define a foo_immediate function". I'm still reading the diff and checking tests -- it's still AI after all.

TIL Rust has an ambiguity `if Foo {}` -- is `Foo` a value of type bool, or a struct? Rust solves this by defining a grammar production 'any expression except struct literals' and using it in this position. https://rust-lang.github.io/rfcs/0092-struct-grammar.html

It's odd how lazy evaluation is generally seen as a niche design choice, yet the vast majority of languages treat `foo() || bar()` as short-circuiting.
