Once the parser has finished calling process_* methods an abstract syntax tree is created. The syntax tree represents the abstract syntactic structure of the parsed source code. Each node in the tree denotes a construct in the source code. This tree is composed of instances of classes defined in lib/compiler/ast/ directory. Each of these classes inherits from Rubinius::AST::Node class. The Node class defines a few methods that are utilized by the subclasses (eg. pos(g) which records the line number for debugging purposes).
