public abstract class Assigner
extends Object

Base class for block assignment logic. This class and all subclasses tries to minimize the amount of conditional logic for doing simple assignment to block parameters during block invocation. The naming conventions for subclasses is the same logic used by the interpreter to represent all parameter types with their arity: pre - Require parameters before the rest argument (if there is one) opt - optional argument (name = value) [1.9] rest - A rest argument is present post - required arguments at the end of the list [1.9] There is also some logic about expanded/non-expanded arguments. This refers to ParserSupport.new_yield and YieldNode expanded attribute.
