Hi Stas! I’m trying to wrap my head around a real-world use-case with this. We have spl_object_hash, which effectively provides a unique hash for an object. If the intent is to provide an opportunity of individual classes to decide what their hash is, couldn’t they provide that via __toString? I know many frameworks use __toString to build out some implementation of an object (Zend form for example), but the point of __toString is to provide a string representation of an object. I want to say, I’m not at all against this - rather I support it. I’m just looking for the RFC to provide an example that I and others can relate to. > It was discussed in the past on the list: > http://marc.info/?t=141145969600001&r=1&w=2 > and I think it makes sense to propose a formal RFC for it.
