ASTs typically discard comments, and that's usually what you want. The only time (AFAICS) that preserving comments is useful is for writing a code formatter. Could you write a formatter in terms of a list of lexemes? A CST is a non-trivial bit of code for one use case.

A funny side effect of building software in Rust: my machine OOMs much more during development. I'm not entirely sure why. I think Rust makes it easy to allocate data quickly, and sooner or later you write an infinite loop when coding.

When writing long-lived programs (daemons etc) in Rust, I find myself asking *where* I should put data. In a GC'd language it's just "I have a string" but Rust forces me to find somewhere to put it. You do get a performance benefit for this work though.
