        * include/bits/valarray_after.h (_Expr<>::operator[](slice)):
        Don't assume the closure implements general indexing, as a matter
        of fact, most of them don't.
        (_Expr<>::operator[](const gslice&)): Likewise.

        (_Expr<>::shift): Fix thinko.
        (_Expr<>::cshift): Likewise.
        (_Expr<>::apply): Likewise.
