Tobie Morgan Hitchcock d4566ff6ea Improve performance with query path analysis
Instead of creating a new Vec<_> for every embedded path part, we now use a reference when calling get/set/del on a value’s data. This means we aren’t creating and copying the Vec items each and every time we traverse down a path.
