Thank you all for your comments.
Here is an illustration of the difference in performance between tacit and
explicit definitions, where there is minimal difference in the computations
demanded by each. Both calculate the mean along the last axis of an array
and both have infinite rank.

Thanks, Ed! Numpy has got what I need for my array manipul
Thank you for all your responses! My thoughts are:
1. Give up engineering and teach J in math classes in schools. This is not
an opportunity open to me, I'm afraid Linda, for several reasons. I think I

I am profiting from a foray into Python, which, it is claimed, is much more
easily understood than J. Some people boast they can program in Python as
quickly as they can type.
