> What are your thoughts? It's a fantastic feature that I've used in Rust, although there are some differences. First, it doesn't work for regular methods -- they have to be part of a trait. Secondly, in general a trait can only be implemented for a given type if it is in the package which defines that type, or in the package which defines the trait. Third, the trait must be in scope. These rules help people understand where the methods are coming from, which is particularly helpful for large code bases or teams.
PHP doesn't really have tools for these kinds of restrictions, but I think it's necessary. You'd need some way to manage where extension methods are loaded, how they are found, and without pessimizing performance of method calls in general just because this feature exists. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: https://www.php.net/unsub.php
