Yes.
Isn't the underlying issue in the above how perl6 handles manipulation
and aliasing of multi-dimensional arrays into derived sub-structures?
In other words, isn't there a more general problem of how to provide
MD access and what to do with the currently one dimensional operations
like:
for (@foo) {
when @foo is multi-dimensional?
Jeremy Howard wrote RFCs that I think relate to this and pointed
me to J (APL cleaned up) as a powerful source of related ideas.
I think the specific issue above relates to a combination of
merge/unmerge and other proposed features.
