Last I checked, Perl 6 had some types that are mutating and others
that aren't (e.g.,

Ok, There's one thing that is not clear in the thread, which is when an
array is multidimensional or not...
For instance:
@a = (1, 2, 3; 4, 5, 6; 7, 8, 9);
Will produce a flatten array, because list assignment causes flattening,
so the dimensionality was lost.
It is important to remember that

No, it doesn't:
@a = (1, 2, 3; 4, 5, 6; 7, 8, 9);
Reflecting on two axes would result in:
@a = (9, 8, 7; 6, 5, 4; 3
I think any 1D op could be transformed to "do the right thing" on a
multidimensional array, with some sort or hyperop or reduction
transform. Rotate, reverse, even add/subtract can be told "do your
thing along this vector" and return a usefully dimensioned result.

Has there been discussion on using array rotate on multi-dimensional
arrays? Being able to pass in a vector as the amount to rotate would
