Expose Internal Representation
elixir
Written February 14, 2016
Elixir is a language that has strong support for metaprogramming. It
provides easy access to an internal representation of the code in the form
of an Abstract Syntax Tree (AST) using maps and keyword lists. The quote
macro is used to expose this internal representation.
> quote do: 2 * 2
{:*, [context: Elixir, import: Kernel], [2, 2]}
> quote do: 2 * 2 == 4
{:==, [context: Elixir, import: Kernel],
[{:*, [context: Elixir, import: Kernel], [2, 2]}, 4]}
