Add all sibling packages of all the packages involved ;-)

If we are not careful we can end up making the compile NP complete.

We just had all the numbers nicely sorted and then someone reads in:

package Foo;
use base qw(Meth_is_1 Other_is_1);

sub Meth ...

sub Other ...

And now we have to recompute the whole tree so that Meth and Other don't
share the index.

Yes - this is why Malcolm dodged MI with 'fields' module.
