For example, I understand that a huge case statement, where each case of
100's may only be 2-6 lines long (can you say "apply production" :-),
will give an enormous McCabe complexity.

It is obviously better coding style for the apply production routine
to break the range up into subranges, and call routines like
apply1to20(), apply21to40(), ..., apply201to220, ...
Much easier to maintain and read :-)

Obviously.
