Again, on the DSE related optimizations.

I'm at t= he Ekoparty where I will show a presentation about security vulnerabilities= caused by compiler optimizations. The subject is more and more serious (e.= g. [1]).

I want to propose to allow [[nodiscard]] = in individual expressions, such as calls to memset(), std::fill_n, and assi= gnments (DSE happens with both memory and registers).

<= /div>
What's DSE?
And what's [1]?=C2=A0<= /div>
