org.jruby.ir.representations.IGVCFGVisitor

public class IGVCFGVisitor
extends Object

Not a double visitor but I did not want both instr and dirgra to have this visitor have an accept added to it. dirgra is external package and instr I can foresee wanting a different visitor altogether not accessed via CFG.
