[Bioperl-l] $obj->clone

[ecky@e-lehmann.de]

Hi,

I had the same problem some time ago... and I found the Perl extension
"Clone" on CPAN.
On C level it copies large and nested data structures even with
references and references to references or Perl objects.
You can inherit from the module and use object oriented style or use
only the function clone() by "use Clone qw(clone);" as the man page
describes...
Here is the link:

Hope it works for you...
