I've been thinking along exactly the same lines. There's a lot of language
issues to consider to get this to work consistently, such as interaction
with reduce(), notation for slices across a dimension (and generalised
slices such as diagonals), and so forth.
I'm thinking that a n-dim array could just be a list of lists (of lists of
lists of...) with the n-dim notation just being syntactic sugar (and perhaps
helping with optimisation too).
BTW, these kinds of issues are well suited to the perl6-language-data list:

I suggest that we cover some 'internals' on that list as well as 'language',
since implementation efficiency is so fundamental in this area.
