Rails delegate example

delegate.rb

class Example
  attr_reader :var

  delegate :del, :to => :instance_var
  alias_method :alias, :del
end

e = Example.new
e.del   # calls e.var.del
e.alias # calls e.del, which calls e.var.del

# I had used alias_method to make the method name look better,
# but it just increased indirection unnecessarily. Hence,
# removing the alias_method call made things simpler but
# significantly less cute.
