and now I know why. But given that's a totally new paradigm for
me (and many) but one I'd like to master all the same, I have a
problem I can solve with an imperative language and wonder how
it's done with a functional language like scad.
Having trouble getting my head around for constructs and how they
might be used to do that if indeed that's the approach, or how to
write a function that works on arbitrary length of the second set
If it's any use, which I doubt, in my use case, L > bn
and bn>an and an>an-1.
I have a gut feel of course that such translations must be
possible, in fact possibly trivial once the mindset is right, but
I'm lacking the insight.
