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

How about https://godbolt.org/z/n11xMd7P3. The comparison ops are missing, as well as the iterator code, but that's pretty much the same as the std version for a single dimension array. It was proposed some years ago for inclusion in Boost but stagnated, then got removed.

That still suffers from {} spam, right? No way to nicely initialize it

without a ton of {}? https://godbolt.org/z/jsTEEbcan
