An introduction to R7
summary
R7 is a new OOP package (on GitHub, aiming for CRAN and core R) that combines S3 simplicity with S4 rigor: generics and methods implement a bizarro generic with four methods instead of a big ifelse, classes are defined with new_class constructors, properties can be active or protected, and multiple dispatch is supported. It adds validator enforces start < end to keep instances valid and remains 100% S3-backward-compatible.
