To whom it might concern,tried to test out this module and got an compile error message. perl -vperl v5.22.1 uname -a4.4.0-128-generic #154-Ubuntu SMP Fri May 25 14:15:18 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux error message :: "qualify_to_ref" is not exported by the Symbol moduleCan't continue after import errors at /usr/local/share/perl/5.22.1/IO/Prompter.pm line 10. There are two ways to resolve this issues - patch IO::Prompter Prompter.PM line 10 use Symbol qw< qualify_to_ref >; to line 10 use Symbol; - patch Symbol.pm line 7 @EXPORT = qw(gensym ungensym qualify qualify_to_ref); line 8 @EXPORT_OK = qw(delete_package geniosym); Solution move qualify_to_ref from 7 to line 8 for export As Symbol.pm is a prerequisite, the first patch is natural, butI assume that Symbol.pm could need a face lift on the API interface Best regardsLutz

I cannot replicate this error under any version of Perl from 5.10 to 5.28. As far as I can detect, Symbol has always exported qualify_to_ref() (at least as far back at Perl 5.10) Is it possible that you have a reeeeeeeally old version of Symbol.pm on your machine? For example, what does: perl -E 'use Symbol; say "version=$Symbol::VERSION from $INC{q{Symbol.pm}}"' tell you? BTW, having qualify_to_ref listed in Symbol.pm's @EXPORT array (rather than it's @EXPORT_OK array) does not prevent it from being imported explicitly. As I cannot replicate the problem and no-one else has reported it in nine years, I suspect something else is going on here. Damian

Thanks for your feedback. I will take a look at it tomorrow. I pointed to the possibility of Symbol.pm and will check it out. - Lutz Show quoted text
