This is a bug report for perl from slaven.rezic@berlin.de,
generated with the help of perlbug 1.34 running under perl v5.8.2.
-----------------------------------------------------------------
The patch 21418 (now not anymore in perl 5.8.2, but still in
bleadperl) breaks some usages of autouse.pm.
Try it with following files:
# Bla.pm: ##########################################
package Bla;
sub foo { warn "foo" }
1;
__END__
# bla.pl: ##########################################
#!perl -x
use UNIVERSAL;
use autouse Bla => "foo";
foo();
__END__
$ perl5.8.2d bla.pl
autoused module has unique import() method at bla.pl line 18
It seems that it will break autouse on every module
not using Exporter.
I see the following solutions:
* Do not apply 21418, but rather deprecate using
use UNIVERSAL
* Fix autouse.pm to not croak if a module uses UNIVESAL::import
* Implement use UNIVERSAL (...) as a special case in the perl
core.
Regards,
Slaven
