Is weird, but what the OP was asking for, actually exist before in the case of FoxPro and similar tools.

In Fox, you write more or less `physical query plans` as syntax:

   USE customer  && Opens Customer table
   CLEAR
   SCAN FOR UPPER(country) = 'SWEDEN'
      ? contact, company, city
   ENDSCAN

And what it make this even better, is that you can also write `SQL` so you can have the best of both worlds.

BTW, I think this idea can be move even further and my take is at https://tablam.org
