You may have had fun, but maintenance programmers or those seeking inspiration or enlightenment would not. Your code contains the same errors that choroba describes, it adds a needlessly nested named sub, a bogus close statement and a nonsensical call to writeOut. The following more conventional code would have served as a simpler and better example:

#!/usr/bin/perl
use strict;
use warnings;

package MyFilehandler;

sub openForRead {
    my ($class, $file) = @_;
    my $self = bless {file => $file}, $class;

    open $self->{fh}, '<', $file or die "could not open '$self->{file}
+': $!";
    return $self;
}

sub DESTROY {
    my ($self) = @_;

    close $self->{fh};
}

sub writeOut {
    my ($self) = @_;
    my $fh = $self->{fh};

    print <$fh>;
}

package main;

my $testfh = MyFilehandler->openForRead('somefile');

$testfh->writeOut();
