Discussion:
Similar to core issue 1270's resolution, 24.3.8.1 [array.overview]/2 should cover aggregate-initialization in general. As it stands, that paragraph solely mentions copy-list-initialization — i.e. it is unclear whether the following notation is (guaranteed to be) well-formed:
std::array<int, 1> arr{0};
[2016-02, Issues Telecon]
P0; move to Tentatively Ready.
Proposed resolution:
This wording is relative to N4567.
Change 24.3.8.1 [array.overview] p2 as indicated:
-2- An
array
is an aggregate (8.5.1) that can be list-initialized withthe syntaxarray<T, N> a = { initializer-list };
where initializer-list is a comma-separated list ofup toN
elements whose types are convertible toT
.
