I programmed in APL a long time ago... even got 'not bad' at it. The best analogy i can give of my thought process is that first i unfolded the problem into one or more many-dimension object(s) ... then took a different "stance" of looking at the object, then refolded them into the final solution. So yes... I had it all in my head at some point.
