Elixir is a functional meta-programming aware language built on top
of the Erlang VM. It is a dynamic language with flexible syntax with
macros support that leverage Erlang's abilities to build concurrent,
distributed, fault-tolerant applications with hot code upgrades.
Elixir also provides first-class support for pattern matching,
polymorphism via protocols (similar to Clojure's), aliases and
associative data structures (usually known as dicts or hashes in
other programming languages).
Finally, Elixir and Erlang share the same bytecode and data types.
This means one can invoke Erlang code from Elixir (and vice-versa)
without any conversion or performance impact.
