21 actually. case, class, data, default, deriving, do, else, if, import, in, infix, infixl, infixr, instance, let, module, newtype, of, then, type, where. There's also three special words that can still be used as identifiers, so aren't reserved: as, qualified, hiding.
OK. Well the list I saw was for Haskell plus extensions, and I visually filtered out the inapplicable stuff. Apparently I missed something.
Also, the number varies depending on whether you consider "reversed words" or "keywords", and I suspect the situation is subtly different
"reversed words"? There are some in sh for example, namely 'fi' and 'esac', but other than that they are not that common... ;-)
for each possible language. I was going vaguely for anything that's hard-wired into a language, and not just part of the standard libraries. (E.g., "return" is definitely NOT any kind of reversed word or keyword.)
