to elaborate further

this:

class Point:
    def __init__(self, x, y):
        self.x = x
        self.y = y

    def inverted(self):
        return Point(self.y,self.x)

could be translated to

class Point;

sub INIT($X,$Y) { 
    $$x = $X;
    $$y = $Y;

    # or $self->{y} = $Y;
}

sub inverted {
    return Point($$y,$$x)

    # or Point->new($$y,$$x)
    # or Point->new($self->{y},$self->{x}) 
    # or Point($self->{y},$self->{x})
    # ... TIMTOWTDI
}

People comming from Python would instantly feel at home and little by little discover more elaborated possibilities by using :attributes.
