I did suggest this method already.
But it really doesn't address the naming clash
class b
{
function print()
{
}
}
class c
{
function print()
{
}
}
class a aggregates b, c
{
}
$a = new A();
$a->print();
you said in the order they were aggregated. but what if i really want to call
c->print();
would i do something like this.
$a->c->print();
and how does this consern serilization. Would it need to be change do designate
which objects are aggregated?
