Feature: some way of getting properties of properties like @alias("primary.nested") or something

[mxndtaylor]

Is your feature request related to a problem? Please describe.
aliasing currently is only grabbing values "flatly" in the sense that it only gets properties of the immediate class it's attached to.

Describe the solution you'd like
a descriptor that repeats the de-aliasing process on it's result based on a series of terms.
some like accepting varargs like *props: str or a path variable with delimiters like "prop.prop"

Describe alternatives you've considered
jsonpath_ng or jq do similar things, but they involve more processing, I just want something extremely simple and straightforward.
