Just tried, it works! This will help me & more importantly some users a lot!
Long history of being bitten by operator priorities, so I tend to go the
"non ambiguous way". Are the operator priorities documented somewhere (I
expect the "standard math ones", but better safe than sorry)

Thanks for the quick answer - I'll fill the Jira. A very small fix would be
to add this to the doc - if the doc is on GitHub I'll gladly submit a PR.
