John already wrote a nice explanation of how array strides work. You mean
specifically for Guile?

Yes, for Guile. I understand strides and offsets. I think the functionality
is basically there
with shared-arrays. So I take back that Guile does not have this. I will play
later.
For example, interesting check will be if one can make a shared-1D array from
the diagonal elements
of a 2D square array (i.e., ((1 2 3) (4 5 6) (7 8 9)) => (1 5 9).
And the transpose I see as a utility that I guess just calls make-shared-array.
