The expression in the Returns element of year::ok in [] p18:

min() <= y_ && y_ <= max()

is ill-formed, as it attempts to compare type short (type of y_ member) with type year (type of year::min() and year::max()).

[2019-06-13; Priority to 0 and Status to Tentatively Ready after seven positive votes on the reflector.]

Proposed resolution:

This wording is relative to N4810.

  1. Modify [] as indicated:

    constexpr bool ok() const noexcept;

    -18- Returns: min().y_ <= y_ && y_ <= max().y_.
