[Pharo-dev] where is the AST?

I am probably misremembering, but I thought I used to be able to do something like... #+ implementors first inspect and spotter would show a CompiledMethod with a tab showing the Bytecode and AST, but I get a RGMethodDefinition that doesn't have those. How do I get those tabs up? This is just for a two minute example for demonstration purposes. cheers -ben
