Um, you do realise you don't need multi dispatch to do operator
overloading don't you?
package Foo;
use overload
'+' => my_add,
...
;
sub my_add {
my $self = shift;
my $target = shift;
$target->add_Foo($self);
}
...
And we can do that today. 'cept it's something of a PITA because
'real' numbers don't respond to object methods.
Every so often I find myself thinking 'I should implement something
that automagically turns all numbers and strings into objects', but
there's always something more important to do.
