I am kind of curious if you have to mentally keep track of the rank/shape/dimensions in your head or if there is some implicit/explicit convention for conveying that to the reader. Does tracking rank/shape become second nature after awhile?
I'm also wondering about things like (APL-style) inner products -- they are undeniably powerful, but it's hard for me to conceptual use cases above rank 3.
