I've brought the tests up to scratch, except for compounds im the parser, because I'm too damn tired to do that over SSH. It looks like collections are right-recursive, whixh was unintended but still works just fine. I've also added the '--verbose' flag to the repl to control the debugging output. Several obscure bugs have been fixed, and comments have been tweaked. Mustfail tests are still needed, but that's a low priority. See #142. Fixed #151
