I am not sure if it faster, but errors could be detected earlier. If the dsl
query language is defined generic enough, the query expression could be
transformed into database specific query strings, or STL/Multindex query
functors, boost::rtl queries or whatever (during compiletime).
One would need two separate query models for relational and tree like
data, to fullfill most needs.
