I've run into a very odd scenario where scoping seems to break something awful. Consider the following examples:
File driver.pl:
use strict;
use TestMeNow;
my %map = TestMeNow::initialize('value', 'Here I am!');
&{$map{'onecase'}{'ex'}}();
File TestMeNow.pm:
use strict;
package TestMeNow;
my(%map, $value, %mapping);
$map{'value'} = \$value;
sub initialize
{
my(%args) = @_;
foreach(keys %args)
{
${$map{$_}} = $args{$_};
}
my $string = <DATA>;
%mapping = eval $string;
return %mapping;
}
1;
__DATA__
'onecase', { 'ex' => sub {print "$value\n";} }
This is an initialization routine I'm using as part of allowing *trusted* user configuration for a script (cut down to see the problem, obviously). Run as is, a newline is output. Adding the line
$value; immediately prior to the eval leads to the correct result, however.
I've found a workaround, but re-reading perlsub leads me to believe this is broken behavior. Has anyone else seen anything similar?
This is 5.8.4, running on Linux.
Thanks,
Cambo
