# We want a uniform way of reducing a code tree
# so the easiest way to do that is to extend
# Object with a call method and whenever any
# object does not define it's own call method we
# assume the object is implicitly claiming it wants
# to return itself. Since Object is almost at the top
# of the hierarchy almost anything we are interested
# in will work as expected.
