Matz, I've got a few lingering questions about Ruby 1.9 and I'm hoping you can provide a definitive answer so I can document them definitively: 1) Will Proc.binding be made to work in 1.9? 2) Will Kernel.__callee__ be implemented so it works as documented in 1.9? If not, may I delete its rdoc comment? 3) Is the new enumerate-by-insertion order of Hash part of the language specification or is it an implementation detail in MRI? (Last time I asked you said you'd see what the JRuby people thought about this.) Thanks! David
