static_assert With No Message

static_assert

This feature adds a new overload for static_assert. It enables you to have the condition inside static_assert without passing the message.

It will be compatible with other asserts like BOOST_STATIC_ASSERT. Programmers with boost experience will now have no trouble switching to C++17 static_assert.

static_assert(std::is_arithmetic_v<T>, "T must be arithmetic");
static_assert(std::is_arithmetic_v<T>); // no message needed since C++17

In many cases, the condition you check is expressive enough and doesn’t need to be mentioned​ in the message string.

Extra Info: The change was proposed in: N3928.
