Today Robert Virding released a new version of his Lisp syntax front-end to the Erlang compiler, which he called LFE (Lisp Flavoured Erlang). I saw the previous versions of his work, and I must say that it is the first version that looks really mature to me now.
LFE is not an implementation of Lisp or even Scheme. Its syntax reflects some specific constructs and limitations of Erlang, since it compiles programs to Erlang bytecode and runs them directly on Erlang VM.
Is a new trend for Erlang coming on?
