Hmmm.   I didn't know about the 3.6 to 3.7 issue.

I use it ... maybe 50% of the time?
Because I'm fantastically lazy with experimental / developmental code, and just
copy existing code from whatever file or open tab is closest at hand.

I have been meaning to get 'round to writing a nice concise isosurface code
block for my Insert Menu stuff, but I haven't gotten there yet.   Maybe by
2021...

If I can remember to do it, I can record times for with/without evaluate in the
future.

Maybe I'll just collect a bunch of functions into an array and see if I can
figure out how to record the render times automagically when I run them all as
an animation.

Is there a way to access and record the max_gradient that was found and write
that to a file?
