Scalar-List-Utils-1.19 I think I should be able to create a dualvar that is partly 'undef'. E.g.: Show quoted text
> perl -MScalar::Util=dualvar -we' dualvar 17, undef ' > perl -MScalar::Util=dualvar -we' dualvar undef, "somestring" 'However, in both cases I get a warning: Show quoted text
> Use of uninitialized value in subroutine entry at -e line 1.If it's a bad idea to do such a thing, it would help if that was documented.
