Short answer: no, and what it gives is quite different.
Long answer:
Erlang gives me two things that are hard to replicate:
1. firm-realtime performance, even at high load: the distributed GC is very
nice
2. a very well defined model for handling, and recovering from failure

This is clearly a job for node.js and the /dev/null data store, since
they are so web scale~

Happstack, Snap) could scale better than Ruby or PHP, and would use
any of those in a heartbeat for such a venture. I'd personally use

Yes I did, in detail. There are two trivial solutions I like:
1. The BERT library (http://bert-rpc.org/) uses Erlang terms for the
protocol, and has straightforward mappings to Haskell equivalents.

This looks rather like ($), but backwards. I believe the F# name for

Odd, since (|) alone isn't legal. Calling it

Working in this direction is a question of taste, but the choice of

On the other hand, my favourite would be :
