Elixir is a functional langauge that crosses many boundaries. With a syntax borrowing heavily from Ruby, a runtime that is on the Erlang BEAM, a macro system like that in Lisp and a streaming library like you might find in Haskell, Elixir borrows the best features from many environments.Elixir borrows from Erlang's "Let It Crash" philosophy, and adds in significant improvements with structs, first-class hygenic macros, and abstractions such as protocols. Still, Elixir is approachable because of its fantastic documentation, clear error messages, and excellent tooling. Many of these ideas were borrowed from other communities such as Ruby, and they make a big difference in langauge adoption
