1) Brand new language inspired by Haskell's syntax, but it is really much closer to ML (strict evaluation, no type classes). More info: http://www.testblogpleaseignore.com/2012/06/21/why-elm/

2) That is totally true! The idea is quite general. I think it works best in a strongly typed language like OCaml or Haskell, but it could work anywhere. FrTime is a Scheme/Lisp/Racket version of FRP. My personal opinion is that it works best in Elm though :P

Briefly, how would you summarize the semantics of FRP in your language as compared to Yampa in Haskell?

A generalization. Arrowized FRP (as introduced in Yampa) can be entirely embedded in Elm.

The Automaton library is the beginnings of such an embedding: http://elm-lang.org/docs/Automaton.elm

To be more concrete, in Elm you can work directly with signals if you want. In Yampa you cannot; you only get "signal functions" (which Elm has as well in the form of Automatons).
