Would be nice to be able to get from an array all items after a given index, without knowing the length of the array. For example:

{ _id :1,
foo: [1, 2, 3, 4, 5]
}

> db.test.find( {}, { foo:

{ $slice: [1, $end] }

} )
>

{ _id: 1, foo: [2, 3, 4, 5] }

Currently, it seems you can only do this by:
1. Knowing what the length is and doing this: db.test.find( {}, { foo:

{ $slice: [1, n] }

} )
2. Using JavaScript in the query
3. Picking an arbitrarily high number to use as the limiter: db.test.find( {}, { foo:

{ $slice: [1, 1000] }

} )
