Still failing with a second unrelated issue.  Looks like wrong code
sent to back-end  (trying to compile an ERROR_MARK) - I probably
exposed a couple wrong handling of errors in the backend through some
refactoring.   What I might end up doing is submitting a new visitor
to walk all trees and assert if an error expression is found, that at
least safe guards me from having to put in workarounds to handle junk
codegen.  :-)
