Why do you want to do this? You'll have to do some
logic in your method body to determine how many
operands you have whether you explicitly pass a list or
whether you have the system break it apart into
separate parameters.

Fredrick Lund's solution, using an * parameter in the
method definition, will produce a list that you have to
pull apart in the method. Doing the same in the method
call takes a single list of all of your parameters and then
distributes it among the parameters in the definition.

I wouldn't bother with either one. Passing a list of my
real parameters as a single parameter is, in most
circumstances, easier and IMO clearer.
