Conditions on key name for projections

[markwylde]

I'm trying to build out dynamic (user inputted) projections and am wondering if there is a way of matching projections via a safe escaping. Like we can do for queries.

For example, should something like the following work?

/* | /{[* = :?],[* = :?]}

Where the values would be ['firstName', 'lastName']

I had a look at the test cases, but couldn't see anything.

Thanks again!
