Code review comment for lp:~zorba-coders/zorba/fix_bug_987830

"empty" and "none" are not valid sequence types. We should try that are modules are at least parsable by other engines as well, so we should use valid sequence types.; For "empty" use empty-sequence(). There is not a valid sequence type for "none", but I did not see it used anywhere. Do you plan to use it? where?

This also means that the code in translator.cpp should be removed.
