>In terms of convention over configuration, Ruby's metaprogramming is crucial for the name-based class conventions that make Rails so convenient. For instance, if you have a class User with the attribute name, at runtime Rails dynamically adds methods to the User class, allowing you to do things like User.find_by_name("Alice"). Rails uses Ruby's metaprogramming capabilities to accomplish this.

This can be accomplished in statically typed languages too. For example, Java has an ORM called Cayenne that generates models based on database tables. You can get similar functionality and ensure you're not accidentally calling something like `find_by_nam`
