Sorry, what I meant was that you would just use 'sub' when you don't
want the enforcement of invocant that either of the first two imply,
i.e. you'd use sub in the perl5 way:
sub dont_care_method {
my $self = shift;
if (ref $self) {
...
} else {
...
}
}
So sub is still just a perl5 sub, where the invocant is passed as the
first arg.
