Subject: [ruby-talk:14793] Polymorphic methods

In C++ you can have polymorphic methods such as

doIt( String s ) {
...
}

doIt( Integer i ) {
...
}

Is there a way to duplicate this behavior without resorting to:

def doIt( object )
    if object.type == String
    ...
    elsif object.type == Numeric
    ...
    end
end

I'm thinking of instances (for example) where you can create an object from
several different objects passed to the constructor. E.g.

m = Month.new(12)
m = Month.new('December')
m = Month.new(anotherMonth)

thus, Month.initialize has to have a case or if statement.

Thanks in advance!

JJ
