Clone::Fast Description

Natively copying Perl data structures Clone::Fast is a Perl module designed as a very optimized version of Clone::More. By taking advantage of one of Clone::More's 'OPTIMIZATION_HACKS' as well as removing all the Pure Perl from the More.pm, I was able to gain a lot of speed out of the module. Essentially, though, the core of the module is exactly as that of Clone::More.You will see that by useing Benchmark::cmpthese, I ran a simple comparison between Storable::dclone, Clone::More::clone, and Clone::Fast::clone. You will (should) begin to see the reason why I loaded this module along side of Clone::More.
