Probably. "It's only a matter of code," as an old work friend would say. :-)

I'm with you on learning best from examples and diagrams. It's on my
list to dig more into the bounding / final internal representations
given I have a list of situations these days where bounding - or lack of
good bounding - is the largest component of a scenes render time.
I've wanted too, to be able to dump the internal representation after
parse and bounding, but no idea when I'll get something like that going.
At the moment focused on the pattern/function cleanup I was working on
late last year - but now in my cut down version of POV-Ray / povr.
