Hi,

A long time ago I wrote a module which seems to work fine. It is a bit like this, but does more.

# OddEffectOfImportTest.pm v1
package OddEffectOfImportTest;

use Exporter;
@ISA = qw(Exporter);
@EXPORT = qw($OddEffectOfImportTest);
our $OddEffectOfImportTest = 6.28;
1;

[download]

... and using it like this is fine.

#!/usr/bin/perl
# OddEffectOfImportTest v1
use strict;
use OddEffectOfImportTest;
print "$OddEffectOfImportTest\n";

[download]

the point being that $OddEffectOfImportTest doesn't have a package name.

Now I've decided it would be useful to help it initalise, so I can use it thus:

#!/usr/bin/perl
# OddEffectOfImportTest v2
use strict;
use OddEffectOfImportTest goreallyfast => 1;
print "$OddEffectOfImportTest\n";

[download]

but when I add "sub import{}" to the module:

# OddEffectOfImportTest.pm v2
package OddEffectOfImportTest;

use Exporter;
@ISA = qw(Exporter);
@EXPORT = qw($OddEffectOfImportTest);
our $OddEffectOfImportTest = 6.28;

sub import {}
1;

[download]

..., without any other changes, I now I get

Global symbol "$OddEffectOfImportTest" requires explicit package name 
+at ./OddEffectOfImportTest line 5.
Execution of ./OddEffectOfImportTest aborted due to compilation errors
+.

Lots of my scripts use this module and I rather not track down and change them all if possible.

Threads 277141 and 569862 looked related but not close enough (for me to understand, at least.

Thanks for any help.
