So I'm looking at GROOVY-4658 <https://issues.apache.org/jira/browse/GROOVY-6458> and I noticed groovy has the --quickstart argument, but no other tools do (in groovy.c). So dumb question: what does that arg do? I can't find any reference to it in the codebase. If it's useful, should any of the other tools have that arg?
