I'm not actually sure anymore about the validity of this code. One can make a
point about the initializer not being a mere string literal.

At least the draft n3126 makes a difference of this, in that an initializer
like "({a, b, c})" is not regarded as a braced-init-list, but rather as a
parenthesized expression-list where the initializer list is handed as one
argument. So I'm unsure whether an initializer like `("foo")` should be
regarded as a string literal or not.

I think I will send an issue report about this.
