Jira issue originally created by user gediminasm:
Currently the only way to set additional parameters accessible by AST TreeWalker is using the query hints.
the main problem is then query is being cloned, hints are flushed and the only way to set them is to access them by name and feed to cloned query one by one.
I think there should be Query::getHints() method available to the userland
