Does the world need yet another Lisp? And in particular, does the world need a Lisp that sits on top of the Erlang VM?  In this talk, Robert Virding introduces us to LFE, or “Lisp-flavored Erlang,” a new version of Lisp built on the Erlang VM.  It’s thus functional and concurrent, but with many of the aspects of Lisp that developers have grown to love over the years. How is it different from other Lisps, including Clojure? And what advantages does it bring over Lisp and/or Erlang itself?  Even if you never use LFE, this talk will introduce you to the ideas of language design, and the use cases for a new language.
