// Exposes a dependency exactly as it is; this is typically the base of a
// composition which was created to serve as one property's descriptor.
//
// Please note that this *doesn't* verify that the dependency exists, so
// if you provide the wrong name or it hasn't been set by a previous
// compositional step, the property will be exposed as undefined instead
// of null.
