@meb_michael I may add that tangent code to the exporter in the future, but I don't want to make the Python code slower than it already is.

@JonOlick Yes and yes. I needed explicitly-sized types, native cross-references, hex/bin/char literals, and comments.

@Reedbeta Second, if && is used as in (x >= min) && (x <= max), then there are two branches unless compiler is clever (don't count on it).

@Reedbeta First, the subtraction max - min is usually a compile-time constant, so it usually doesn't even count.

Remember that integer range checks can always be done with only one comparison: (unsigned) (x - min) <= (unsigned) (max - min)

@BillB The takeaway is that lots of people in all industries somehow get into a position to judge despite being staggeringly incompetent.
