Tricks of the Wizards

Globjects

The constructor is similar to the previous example:

        package IO::Remembers;        
        sub new {
          my ($package, $filename) = @_;
          open my $fh, $filename or return; 
          bless $fh => $package;
        }

Once again it can be used like a regular filehandle:

        my $fh = IO::Remembers->new('input');
        my $line = <$fh>;
        read $fh, $bytes, 1024;
        close $fh;
