Help docs on [1,2,3,4]!

[LukyGuyLucky]

May I ask what does '!' do here? and ,where can I get relative documentations regarding on this topic?

fn test_any_all_of_ints() {
	ia := [1, 2, 3]!

	assert ia.any(it > 2)
	assert ia.any(|x| x > 2)
	assert [1, 2, 3]!.any(it > 2)
	assert [1, 2, 3]!.any(|x| x > 2)

	assert !ia.all(it > 1)
	assert !ia.all(|x| x > 1)
	assert ![1, 2, 3]!.all(it > 1)
	assert ![1, 2, 3]!.all(|x| x > 1)

	assert ia.any(it == 2)
	assert ia.any(|x| x == 2)
	assert [1, 2, 3]!.any(it == 2)
	assert [1, 2, 3]!.any(|x| x == 2)

	assert !ia.all(it == 3)
	assert !ia.all(|x| x == 3)
	assert ![1, 2, 3]!.all(it == 3)
	assert ![1, 2, 3]!.all(|x| x == 3)
}

Thanks.

[1, 2, 3]! is a syntax for fixed size arrays https://docs.vlang.io/v-types.html#fixed-size-arrays

In the future, there are plans to change this syntax to another one, as it is confusing for many people #25183
