module Mutant

# A method object for inserting an AST into the Rubinius VM
|
|
#
|
|
# The idea is to split the steps for a mutation into documented
|
|
# methods. Also subclasses can override the steps. Also passing
|
|
# around the root node is not needed with a method object.
|
|
#
|
|
# As the initializer does the work there is no need for the
|
|
# instances of this class to be used outside of this class, hence
|
|
# the Loader.new method is private and the Loader.run method
|
|
# returns self.
