LFE (programming language)

LFE (Lisp Flavored Erlang) is a functional, concurrent, general-purpose programming language and Lisp dialect built on top of Core Erlang and the Erlang Virtual Machine (BEAM). LFE builds on top of Erlang in order to provide a Lisp syntax for writing distributed, fault-tolerant, soft real-time, non-stop applications. LFE also extends Erlang to support meta-programming with Lisp macros and an improved developer experience with a feature-rich REPL. LFE is actively supported on all recent releases of Erlang; the oldest version of Erlang supported is R14.
