currying in perl6

[Matthew D Swank]

I apologize if this has already been addressed, but given the following
definition:

sub make-adder ($a){
    sub ($b) {
        $a + b$;
    }
}

make-adder 5

returns a closure, however pugs won't parse:

make-adder 5 6

or:

(make-adder 5) 6

I have to resort to:

(make-adder 5)(6)

Is this correct behavior?

Thanks,
Matt
