---------------------------------
Hi, [~vihangk1], thanks for your review. The patch is updated according to your
comments, and I also left some comments to clarify some problems on the review
board.
For the qtests, I think Vectorizer doesn't support complex type for MapWork
currently, so qtests can't be added for now. I plan to create a new JIRA for
this support and add qtests in that ticket, what do you think?
