Counter-intuitively, if you're writing a parser for a programming language, you need it to be a total function. As soon as you build IDE tooling, you need ASTs from invalid or incomplete input. The parser should return (Ast, List<Error>) rather than Result<Ast, Error>.

Deno has the cutest PL mascot I think I've ever seen. Are there any other contenders?

I frequently find myself running: $ slowish $ slowish | jq $ slowish | jq | grep I feel there must be a better way to build up pipelines incrementally without re-running. I could save each output to a file, but it's more verbose, and most of these tools have nicer output when stdout is a TTY.
