Subject: Variable argument number and behaviour [Newbie]

Hello Everyone,

I'm trying to make a function take arguments in a particular way.

This is what I want to create:

#Variable argument testing
def function(*sometimes)

  if sometimes.nil?
    print "Not given!"
  else
    print "Here!"
    end

  end

function
[EOF]

As I understand it, the * operator bundles the argument into an array,
so that if test returns true. I know that I can use "if
sometimes.length==0" to get the same behaviour, but that is rather
obscure compared to the first version.

Is there some other way to set up the argument list? (Alas, I have found
nothing in the documentation or the Forum.)

Thank you,
-Ryan
