I think it's a misunderstanding based on the fact that Erlang was originally implemented in Prolog, so in some ways the language features are superficially similar - pattern matching and single assignment come to mind. Regardless of where it came from, though, it really is ugly. But it does get the job done, and the rules aren't that hard to learn. They're actually pretty simple, and with the right emacs mode it's pretty hard to mess up. http://www.sics.se/~joe/pubs/prac_appl_prolog.ps http://www.sics.se/~joe/pubs/prac_appl_prolog.ps
