Ive been experimenting with adding a questionable feature to Data::Dumper::EasyOO-0.03_01 (on CPAN), ie: passing a $var to import(), which initializes it with an object thats then available for the (lazy, and arent we all) user:
my ($mdd, %style);
BEGIN { %style = (indent=>1, autoprint=>1) };
# 1st 2 work, last doesnt !
use Data::Dumper::EasyOO ( %style, init => \$mdd);
use Data::Dumper::EasyOO ( %style, init => \our $odd);
use Data::Dumper::EasyOO ( %style, init => \my $ndd);
$mdd->(mdd => \%INC);
$odd->(odd => \%INC);
$ndd->(ndd => \%INC);
I expected 3rd way to work just like the others, by creating a my variable in main. In support of my expectation, the following works, almost analogously, except for the use-time action.
perl -e 'sub f{my$p=shift;$$p++;} f(\(my ($g)="val")); print "g:$g\n"
+'
thanks in advance for your insights, and I take bug reports ;-)
