Hi Mike, From a userland perspective I don’t really “get” your proposal. It seems like you’re trying to allow for type conversions in a predictable manner, but in a very different way than php already does that with built in types and interfaces (__toString, the proposed __toArray, plus the various (de)serialiser options) Your proposal seems to imply some kind of automatic method generation by the engine itself (or the examples are all missing that boilerplate??) which is very non obvious to me and I think would be to others too. From my perspective a more obvious solution for this type of thing (and I’m not necessarily sure I’d use the feature myself to be honest) would be a set of interfaces (or magic methods to match __toString but I know they’re less preferred by some these days) to define that a class can be safely cast to another type when used with typed properties/arguments/returns.
