# Virtual
# Object Oriented
# Langiage
#
# VOOL is the abstraction of ruby, ruby minus some of the fluff
#      fluff is generally what makes ruby nice to use, like 3 ways to achieve the same thing
#      if/unless/ternary , reverse ifs (ie statement if condition), reverse whiles,
#      implicit blocks, splats and multiple assigns etc
#
# Also, Vool is a typed tree, not abstract, so  there is a base class Statement
#            and all it's derivation that make up the syntax tree
#
# This allows us to write compilers or passes of the compiler(s) as functions on the
# classes.
module Vool

  # Base class for all statements in the tree. Derived classes correspond to known language
  # constructs
  #
  # Compilers or compiler passes are written by implementing methods.
  #
  class Statement

      arr << self

    def to_mom( _ )
