Subject: Re: passing method references in python & ruby

In python when you use method name without parenthesises you get
method reference. In Ruby it won't work beacuse method can be called
without parenthesises (and Ruby programmers love it :)). If you want
to get method reference you can use method(:you_method_name) and you
get reference to Method instance. Later you can just call 'call'
method and pass some parameters. Direct traslation of your program to
Ruby looks like:

def firstWay(arg1, arg2)
  return 'Tastes great.'
end

def secondWay(arg1, arg2)
  return 'Less filling.'
end

def doStuff(whichway, first_arg, second_arg)
  return whichway.call(first_arg, second_arg)
end

puts doStuff(method(:firstWay), nil, nil)
