Re: Multiple instances of the same base class

[Riales]

Usually, whenever you call a package's new method, it should already be returning a brand new instance of itself, so I would think what you have is already mostly correct.

Some other things I noticed though...

I think instead of:

use BasicX;

You actually want:

use base BasicX;

This is because use base establishes a ISA relationship for between your current class and the specified base class(es).

Beyond that, change this section:

my $newclass = BasicX->new(...);

To something like this:

my $newclass = $class->SUPER::new(...);

That should work properly.
