 where the layout() function is already capable of computing the
 required overall width based on the (newly-computed) vec_el_widths.
 
+Note that, interestingly, when fixed_width priority SimdShapes are
+used on both LHS and RHS, it is effectively an identical case to
+when the RHS is an integer, because the fixed_width of the RHS is
