Sure, Bart, the first implementation of Erlang was as a
prolog interpreter. Thereafter ...

However, this is not to say that Erlang more than other
functional languages was significantly _influenced_ by
Prolog. It simply means that Prolog was taken in use as
a prototyping tool -- and a fine one it is.

I think you should have a look at the history of Erlang and
appreciate the fact that Erlang at first had commonalities with
Prolog (it was more than just being implemented by a Prolog interpreter).
Sure, quite soon, the authors decided to take out backtracking and logical
variables. But that does not mean Erlang was not influenced heavily by
Prolog. First of all: being influenced doesn't mean having much in common.
Secondly, LISP (just to name one functional language) certainly wasn't
influenced by Prolog as much as Erlang - you should be able to see that at
least. Finally, please, name a functional language that was more
influenced by Prolog than Erlang.
