No problems! :-)

Just I want to be sure that you realize that exists SQL way.

Just BitSets and ArraySets - this is the main low-level tools of Valentina
engine. We self use them in our SQL engine.
 
In Valentina 2.x we have open these tools to all developers.

They are more powerful, while require more coding and "think different" :-)

This is right. Using sets it is possible write more effective data
manipulations.
