[Martijn Lievaart]

Martijn> Better written as:

Martijn> $self->kick();

Martijn> although if kick() does not exist, the former fails at compile
time while Martijn> the latter fails at run time.

And if kick doesn't know what to do with an object of the type that
$self is, it'll have to check that itself unless it's a method call.

OK, so which one is preferable:

shoot($self, $foot);

or

$self->$shoot($foot);



Or should we introduce some form of double dispatch here, so

shoot($self, $foot);

depends both on the type of $self as the type of $foot?.
