When should you prefer Moo, and when should you avoid it?

When considering object-oriented programming in Perl, Moo is an excellent choice for many use cases. It is lightweight and simplifies the creation of classes while providing moose-like features without the overhead. However, there are scenarios where you might want to avoid Moo in favor of more complex solutions like Moose or using plain Perl. Here are some guidelines on when to prefer Moo and when it might be best to avoid it.

When to Prefer Moo

If you need to create simple object-oriented classes quickly.
When you are working on small projects or scripts where performance and simplicity are more important than advanced OOP features.
When you want to minimize dependencies, as Moo has fewer requirements compared to Moose.

When to Avoid Moo

If you require advanced features like type constraints, more complex attributes, or meta-programming capabilities, which are better supported by Moose.
For larger projects where you benefit from Moose's more extensive ecosystem of extensions and community support.
When building a project that demands strict adherence to OO practices and patterns that Moo may not strictly enforce.

Example of Using Moo


            use Moo;

            package Person {
                use Moo;
                
                has 'name' => (
                    is  => 'ro',
                );

                has 'age' => (
                    is  => 'rw',
                );
                
                sub greet {
                    my $self = shift;
                    return "Hello, my name is " . $self->name;
                }
            }

            my $person = Person->new(name => 'John Doe', age => 30);
            print $person->greet(); # Outputs: Hello, my name is John Doe
