[Bioperl-l] $obj->clone

[Hilmar Lapp]

They also refer to the (allegedly - not surprisingly - slower) 
Storable::dclone -- that in fact sounds appealing to me as it's pure 
perl, and I believe we have a dependency on Storable already.

Hm... so deep-cloning (again, not surprisingly) is a solved problem 
then ... no need to integrate this into bioperl -- or would it be 
better to have our own clone() method in Root.pm that just delegates 
to Storable's dclone()? We have taken this route in the past, makes 
accommodating different platforms and perl versions easier.
