When should you prefer module version numbers, and when should you avoid it?

In Perl, version numbers in modules are essential for managing dependencies and ensuring compatibility. However, there are cases where you might want to avoid specifying them to maintain flexibility. This guide will help you understand when to use module version numbers and when to refrain from doing so.

# Example of using version number in a Perl module
package MyModule;
our $VERSION = '1.0.0';

sub new {
    my $class = shift;
    return bless {}, $class;
}

1; # End of MyModule
