Subject: Re: [std-proposals] Fixing C-style arrays
From: Maciej Cencora (m.cencora_at_[hidden])

Please read my proposal carefully yet again. I am not proposing to
deprecate core functionality used by millions lines of code.
I am only proposing to deprecate such uses of C-style arrays that lead to
bugs.
