require 'citrus'
module Citrus
module GrammarMethods
# Permits creation of aliases within rule definitions in Ruby grammars using
# the bare name of another rule instead of a Symbol, e.g.:
#
# rule :value do
# any(:alpha, :num)
# end
#
# can now be written as
#
# rule value do
# any(alpha, num)
# end
#
# The only caveat is that since this hack uses +method_missing+ you must
# still use symbols for rules that have the same name as any of the methods
# in GrammarMethods (root, rule, rules, etc.)
