Browse source 
* module/language/cps/compile-bytecode.scm (compile-function): Always
  define a 'closure binding in slot 0.
* module/system/vm/frame.scm (available-bindings): No need to futz
  around not having a closure binding.
* module/system/vm/debug.scm (arity-arguments-alist): Expect a closure
  binding.
* test-suite/tests/rtl.test: Emit definitions for the closure.
