| Gaby, could you please provide an update about this PR?

I think I gave all necessary information in the initial analysis I
made. Did you find something is out of date?

Personally, I would resolve this as won't fix, or at least suspend. 
There is a trivial workaround

    char some = foo(&valarray<char>(y.apply(bar))[0]);
