This is needed because there is no way to cast the output in the middle of the chain.

This is not be done on _.pluck() methods because T cannot be inferred.  In other words, this:

    <number>_.pluck(objectArray, 'id');

or this:

    var id: number = _.pluck(objectArray, 'id');

is cleaner than this:

    _.pluck<IMyObjectInterface, number>(objectArray, 'id');
