If you forget about exporting your functions, you can try this:

package Foo;

# constructor
sub new {
    my $klass = shift;
    # maybe take arguments from @_
    my $self = bless {}, $klass;
    return $self;
}

sub bar {
    my $self = shift;
    my ($param1, $param2) = @_;

    if (ref $self) {
        # we are an object instance
        print "hey, I'm an object\n";
    }

    return ($param1 == $param2);
}


# and how to use it
package main;

# procedural
Foo->bar(6 * 9, 42);

# OO
my $f = Foo->new();
$f->bar(15 * 17, 255);
