c++ - Design decision regarding std::array fill -

-

std::array in c++11 useful class provides c++ container interface on c stack array.

but why std::array not have typical fill constructor containers have? instead, has method fill.

is there reason why std::array unique among stl containers in regard?

from section 23.3.2.1:

an array aggregate (8.5.1) can initialized syntax array = { initializer-list };

if worked std::vector wouldn't pod anymore. additionally same section:

the conditions aggregate (8.5.1) shall met.

these conditions are:

an aggregate array or class (clause 9) no user-provided constructors (12.1), no brace-or-equalinitializers non-static data members (9.2), no private or protected non-static data members (clause 11), no base classes (clause 10), , no virtual functions (10.3).
