Most (but not all) parameters act as default values for re

Certainly you can pass a parameter to a keyword argument, and/or make a
parameter the default value of a keyword argument. And you can use an
argument to parameteriz

The parameters should not be different. The objective of the save/restore
parameters is to make sure

Right, so make-bm is being called from another thread and so the parameters
are different there.
That explains why in this case, the axes are hidden:

Thank you. I am not technically sufficient to add much to your response.

Your criticism of SICP's use of recursion seems to extend to the method for
teaching recursion principles in The Little Schemer series, in that it does
just that - teaches
