Subject: Kills DBHs

After cloning, my DBI database handles barf with: Can't call prepare method on handle DBI::db=HASH(0x25755c8) after take_imp_data() at ../lib/Radio/Four/Programme.pm line 104.

A DBH is something can't be cloned (at least by Clone) since there are too many underlying objects like C structures, file handles, etc that Clone doesn't handle. A DBI database handle does have it's own clone method. I have considered having Clone check an object for a native clone method and using that in preference of it's own, but I think it might be a little too ambitious for me.

Having Clone check a blessed reference for a clone method should be really simple, using UNIVERSAL isa, so why not give it a shot? Sounds like a great return for a little investment...! Just a thought. I could supply you a patch ? Lee -- Lee Goddard Server-side Systems Ltd London N1 :: 0208 369 6832
