Meteor Mongo fields aliases

Hi!

How can we do something like

db.Collection.find({}, { fields: { "fooAsBar" : "$bar" } })

I thought this would’ve worked, but it does not. I’ve tried all variations and even grepped for project* and fields in https://github.com/meteor/meteor/blob/master/packages/mongo/collection.js#L309 but no dice.

Is the only way to use aliases via rawCollection?

Thanks!
