Re: Importing variables (not functions) from in-file packages

[AnomalousMonk]

Your original code seems to work as long as the scalar  $globalVar is exported using its correct name, i.e., using the  $ sigil.

c:\@Work\Perl\monks>perl -wMstrict -le
"MyPackage->import;
 print $::globalVar;
 $::globalVar=1;
 print $::globalVar;
 myfunction();
 BEGIN{
   package MyPackage;
   require Exporter;
   our @ISA = qw(Exporter);
   our @EXPORT = qw($globalVar myfunction);
   our $globalVar = 42;
   sub myfunction { print 'hi from ', __PACKAGE__; }
   }
"
42
1
hi from MyPackage

Cool. It does indeed work. But why does strict cause the compiler crap-out on $globalVar but accept $::globalVar. Isn't $globalVar (when not defined as a lexical variable) just a shortcut for the (main) package variable $::globalVar aka $main::globalVar? Or is the "shortcut" only known at runtime...

Isn't $globalVar (when not defined as a lexical variable) just a shortcut for the (main) package variable $::globalVar aka $main::globalVar?

It is a 'shortcut' only if you make the lexical declaration
    our $globalVar;
Then if the first access of the package variable  $globalVar is after the declaration, everybody's happy; otherwise, the variable name must be fully qualified. See our.

Because that is what you asked it to do with  use strict 'vars';
