Thank you Parkinbot!
This is an excellent example of how a user new to OpenSCAD could spin
their wheels "needlessly". I know nothing about the internals of
OpenSCAD. I imagine that most C programmers do not wish to have to
understand the details of the parser or the code generator. I hope that
we can eventually have a tool where two seemingly identical structures
take roughly the same time to calculate. I imagine there are good (and
subtle) reasons why this objective is difficult to achieve
