2b59e3df49Currently, we convert the properties of a rule into parameters and pass them to the exceptions. That complicates things for a few reasons: 1. The exception knows too much: there's a lot of information in an object, and the exception would only need a few parameters to work correctly. 2. Any variable change becomes a backward compatibility break: if we change the name of the variable type in a rule, even if it's a private one, we may need to change the template, which is a backward compatibility break. 3. The factory is bloated because of introspection tricks: it reads the properties from the class, even from the parent, and then passes it to the exception. Of course, that means we introduce another method to `Validatable`, but in most cases, extending `AbstractRule` is enough to create a new rule. Signed-off-by: Henrique Moody <henriquemoody@gmail.com>
