[cfe-dev] Curious about libcxx __libcpp_nmstr design

[Yaron Keren]

I have couple of questions about __libcpp_nmstr class design.

It's a reference counted char* class optimized for size, right?

Why is this so important to optimize this class size to the absolute
minimum?

What is the purpose of the two unused_t? (I understand they are named
unused...)
Why they are assigned the string length if never used?
