Today I learnt that the original name for DOS was QDOS, for "Quick and Dirty Operating System"! https://en.wikipedia.org/wiki/DOS#QDOS (Seems rather unfortunate that they dropped the Q.)

Today I learnt that `cargo fix` won't fix code with compiler errors by default, but you can override this! $ cargo fix --broken-code --allow-dirty && cargo clippy --fix --allow-dirty This incantation does exactly what I wanted :)

What are the most popular languages that have used an AST walker for their implementation? I know Ruby used to do this, but there must be others. (I'm interested in the lowest PL speed that users will tolerate if you have awesome features.)
