All I'd Wanted to Know about Ruby's Object Model Starting Out...and Mooar!!!
summary
Walks the CRuby C source (specifically CRuby 2.4 source) and shows the actual structs – RBasic/RClass structs with flags, kclass pointers and method tables – then traces bootstrapping in init_vm, the rv_define_class_id path that creates classes and method classes, and the convoluted make_metaclass logic that spawns meta/meta chains. Demonstrates singleton-class creation (much simpler), how include classes are inserted and share module method tables, and why Ruby’s class/superclass methods skip singletons and include classes.
