Re: [boost] Does anybody know why boost::array does not support multiple dimensions?

In my opinion this is very ugly since end users will just get angry and frustrated and switch to something else most of the time, but at least it seems equally ugly as nested std::array, so no "regression".

I didn't think about the recursion approach, so I suppose you can have a generic implementation. Though it would seem it should be rather expensive in terms of compile times. Here's a prototype: https://godbolt.org/z/sj1Trs1TE It would need more work if you want references and iterators to work in terms of arr<> and not the built-in arrays.
