Module definition problem

I'm trying to define a module:

package Foo;

use strict;

require Exporter;

our @ISA = qw(Exporter);
our @EXPORT = qw(bar);
our $VERSION = "1.0";

sub bar() {
    my $val = shift;

    print $val;
}

1;

However when I try to use the bar function as follows:

use strict;

use lib 'E:/Programming/Perl/libs';
use Foo;

bar("Test");

I get the following error:

Too many arguments for Foo::bar at test.pl line 6, near ""Test")"
Execution of test.pl aborted due to compilation errors.

What's going on here?

You used the prototype bar() which means that bar has no arguments.
You probably wanted either

sub bar($) {
    my $val = shift;
    print $val;
}

or

sub bar {
    my $val = shift;
    print $val;
}

Thank I would have stared at that for 4 or 5 more hours before picking it up.
