Resenting due to mailing list failure yesterday. ----
Morning Internals, I just opened the vote on "Parameter Type Widening", initially named "Parameter No Type Variance". RFC: http://wiki.php.net/rfc/parameter-no-type-variance Voting will keep open for three weeks and close on 30th of January, probably in the evening of UTC. You can find an excerpt of the RFC below. ---- PHP currently doesn't allow any variance of parameter types when checking whether a method implemented in a class is compatible with the method defined either in the parent class or interface. This RFC proposes to allow omitting a type entirely in a subclass, as dropping all parameter constraints is always valid according to the contravariance rule. Implementing this RFC would allow libraries to be upgraded to use type declarations in their method signatures. Currently adding types to a method of a class in a library would break any code that extends that class. This would provide an easier upgrade path for libraries to start using scalar types, to replace manual checks being done inside the methods, without requiring an update for all sub-classes. ---- Kind Regards and Happy Voting, Niklas Keller
