As a language user and a package maintainer it would be a huge problem. Imagine how would be to maintain a package that can be used with both strict and coercive type checking. We would have to write 2x more tests and yet pollute code with manual type checks (is_string, is_integer) for the non strict runtime mode when type check is necessary. I don’t see why this would create “mutant” or “buggy” behaviour. You always get the type you ask for: the weak behaviour is precisely the same as in v0.1. The strict behaviour is fairly intuitive. In no case will you ever receive the wrong type. I don’t understand. -- Andrea Fauld s Hello Andrea! Consider what a mess was register_globals and problems it had, but at least it was a global setting. Declare will work on per file basis, and it will end up even more of a mess. I think PHP development community learned that lesson and that's why you get pushback, and not only from internals, but also from the userland. Me including. Rergards, Arvids.
