$Data::Dumper::Deparse or $OBJ->Deparse([NEWVAL])

Can be set to a boolean value to control whether code references are turned into perl source code. If set to a true value, B::Deparse will be used to get the source of the code reference. Using this option will force using the Perl implementation of the dumper, since the fast XSUB implementation doesn't support it.

Caution : use this option only if you know that your coderefs will be properly reconstructed by B::Deparse.
