Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:
I'm trying to export a reference to a hash but can only access it with a fully-qualified name. What am I doing wrong? Thanks
Package Foo; use strict; use warnings; use Exporter 'import'; our @ISA = qw[Exporter]; our @EXPORT_OK = qw[%env $env]; our %env = %ENV; our $env = \%ENV; 1;
perl -I. -MFoo=%env -le 'print scalar keys %env' 38 perl -I. -MFoo=$env -le 'print scalar keys %$env' 0 perl -I. -MFoo=$env -le 'print scalar keys %$Foo::env' 38
