Spent at least an hour trying to debug this ocaml function, only to realize "end" was a reserved word that my text editor didn't highlight. Classic.

So annoying. I've had similar, especially when working with legacy MySQL databases with reserved words used as column names. Reserved words are annoying so I started trying to prefix/suffix anything that seems like it can even remotely be a reserved word.

Good idea. Thanks!

That is why I think that a good programming language has no reserved words.

"let x = y in z"

is "y |> fun x -> z"

Why not "x |> .\ y -> z"
