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;

[download]
You actually want: 
use base BasicX;

[download]

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(...);

[download]
To something like this: 
my $newclass = $class->SUPER::new(...);

[download]
That should work properly.
