I don't think "Weak Interfaces" became an RFC unless Google is failing me, but I found a reference to it being on the mailing list from Matthieu Napoli's article on GitHub about decoupling, which is worth a read: https://github.com/mnapoli/mnapoli.github.io/blob/master/articles/decoupling-packages.md As far as Go's implicit interfaces, I have found that to be one of the most compelling language features of Go, and would be ecstatic if we could find a way to support implicit interfaces in PHP. -Mike
