Thank you very much Janek!
I found these bugs too and wrote to [EMAIL PROTECTED] but don't know why it is
not sent out. And I wrote to the writer but no response :(
In fact, it should use to specify it:
@ISA = qw(Heap::Fibonacci);
The Heap package is a front end class and use Heap::Fibonacci in disguise.
Thank you once again!
