Thank you for the assistance.

I am using Perl 5.24.0.

The problem is with reading from the IO::File object stored in the hash. All other portions of the example code work correctly.

Using readline, as suggested by BrowserUK fixes the problem; however, I do not understand why storing the IO::File object in a hash vs storing it in a scalar should have any affect. There must be some syntatic trick I am missing.

Sample 3:

use Path::Class;

my $filename = "data.txt";
my $object = file($filename)->open('<:encoding(UTF-8)');
my %hash = ( 'handle' => $object);

my $line1 = <$object>;
my $line2 = readline($hash{'handle'});
my $line3 = <$hash{'handle'}>;
my $line4 = <{$hash{'handle'}}>;

print $line1, "\n";
print $line2, "\n";
print $line3, "\n";
print $line4, "\n";
close($object);

Sample 3 Output:

IO::File=GLOB(0x4de178)
IO::File=GLOB(0x4de178)
