About LFE

What LFE Isn't

Just to clear the air and set some expectations, here's what you're not going to find in LFE:

• An implementation of Scheme
• An implementation of Common Lisp
• An implementation of Clojure

As such, you will not find the following:

• A Scheme-like single namespace
• CL packages or munged names faking packages
• Access to Java libraries

What LFE Is!

Here's what you can expect of LFE:

• A proper Lisp-2, based on the features and limitations of the Erlang VM
• Compatibility with vanilla Erlang and OTP
• It runs on the standard Erlang VM

Furthermore, as a result of Erlang's influence (and LFE's compatibility with it), the following hold:

• there is no global data
• data is not mutable
• only the standard Erlang data types are used
• you get pattern matching and guards
• you have access to Erlang functions and modules
• LFE has a compiler/interpreter
• functions with declared arity and fixed number of arguments
• Lisp macros
