R7 is a new object system implemented as an R7 package on GitHub that aims to merge S3 simplicity with S4 rigor and eventually become part of R. It provides new_generic and method for generics (example: a bizarro generic with numeric logical character methods where numeric expands to integer and double so printing shows four methods), new_class constructors with active properties and a validator that enforces invariants; multiple dispatch and S3 compatibility are implemented and the package is usable now.
