This is the case for most functional languages (the subset of functional languages which are *pure* is pretty damn small, if you actually look it up). And even "pure" functional languages (e.g. Haskell) have to deal with the outside world at some point.

That sequential erlang is a functional language is a plain and simple fact, it just isn't a *pure* functional language. But that's a different bucket of filth.
