The problem of querying hierarchically-ordered data has been around for 
a long time, and XQuery is a popular solution (at least when that data 
is XML).

Of course associative arrays are simpler than XML, so any XQuery-like 
solution crafted for LC could be even simpler to use.

But XQuery is quite powerful, probably a good model to consider for 
handling the variety of use-cases we'd want such a generalized query 
system to handle.
