Strip IDs from queries

[mxstbr]

With either of the callbacks it'd be great to have an option to get the query string without any IDs. What I mean by that is that instead of getting this:

r.table('users').get('max').run()

I want to get this, no matter which ID is passed in:

r.table('users').get(id).run()

That could be useful since in many cases I don't particularly care which specific record was loaded, only how fast the query is overall.

There's likely some edge cases I haven't thought of where this won't work, but it could still be a nice enhancement!
