A curried lambda returns false for #lambda? despite having identical 
"rigid" argument handling.

    >> l = lambda {|x|}
    => #<Proc:0x9914b60@(irb):33 (lambda)>
    >> l.call(1,2)
    ArgumentError: wrong number of arguments (2 for 1)
  from (irb):34:in `call'
  from (irb):34
  from /usr/local/bin/irb:12:in `<main>'
   >> l.lambda?
   => true
   >> l.curry.lambda?
   => false
   >> l.curry[1,2]
   ArgumentError: wrong number of arguments (2 for 1)
  from (irb):37:in `[]'
  from (irb):37
  from /usr/local/bin/irb:12:in `<main>'
