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

Can be set to a boolean value to control whether code references are t
+urned 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 wi
+ll 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.
