説明
Our lowering code for expressions is a single giant match, and looks like it consumes a lot of stack space, even in release mode.
See https://github.com/rust-analyzer/rust-analyzer/pull/5316/commits/12d52a726a1e6ca0f6b08343d13d0f6b50d94d8c for some ways to observe this.
It would be nice to optimize this!
