Why so harsh?

Was there a debate when `rx' made it to the Emacs core?  It's an
alternative syntax (which actually I still haven't learned, because,
unlike `short-lambda', `rx' is actually hard to learn) for a string
regex. There's nothing like it in other PLs, unlike the string
regexes, which most of PLs feature.

So how do I deal with `rx' when I encounter one?

    with C-x C-e

So how can you deal with #(* % 2) when you encounter one?

    with C-x C-e: returns "(lambda (%) (* % 2))"
