Subject: Re: [std-proposals] Fixing C-style arrays

Yes, I am fully aware of std::array but it does not fix the C-style arrays,
it just provides another solution for stack-based const size arrays (and
one that does not always work as expected due to brace-elision preventing
correct deduction of constructors being called for each element).

I am proposing to fix C-style arrays. I don't want yet another const size
array container (and especially the one that slows compilation time due to
template bloat).
