As you now know [https://www.crustofcode.com/how4/], quote descends the syntax tree that is its argument and converts it into code that will, when executed, build the original syntax tree. quote is usually not useful unless the tree contains unquote or unquote_splicing nodes. This post explains how

When the Elixir parser sees quote do: content, it produces a 3-tuple of the form {:quote, metadata, [[do: content]]}. Marick takes a deep breath. :quote is a special form that takes the abstract syntax tree content (which represents Elixir code) and turns it into an abstract syntax tree for

The previous post showed how code is represented as syntax trees. This one shows how literal data like %{a: 3} are represented.

The last post looked mainly at the different binding maps that are created and used during bytecode generation. This post looks at the syntax trees that are parsed from Elixir text, then delivered to the bytecode generator.

As Abraham Lincoln did not say: those who like this sort of thing (details of programming language implementation) will find this the sort of thing they like.
