Er, I thought we were talking about setting named parameters, not 
default values.

        sub foo ($name = 'Fred', $age = 32) {   # defaults
            # do stuff with $name and $age
        }

        foo('Barney', 31);              # Positional assignment
        foo($age:31, $name:'Betty');    # Named assignment
        foo($age:=31, $name:='Betty');  # Named assignment v2

        foo($age||=31, $name||='Betty');        # NO
        foo($age=>31, $name=>'Betty');          # NO, etc.
