Array + Boolean

Hi, that's something that bother me sometimes, when I'm using blender wrongly to do CAD :

I can't self-boolean on an array. I can merge vertices by distance, wich is cool. But I often meet intersecting geometries that can't be solved only my removing vertices by distance. My suggestion is : An option for self boolean (make a boolean intersection of all members of the array) and clipping at a certain distance (same as mirror). What do you think of such an idea ?

Thanks ! Best Regards !
