}

fn main() {
	assert count_str(['one', 'two']) == 2
	assert count_str([]string{}) == 0
	assert count_str([]) == 0

	assert count_int([1, 2]) == 2
	assert count_int([]int{}) == 0
	assert count_int([]) == 0

	assert count[f64]([1.0, 2.0]) == 2
	assert count[f64]([]f64{}) == 0
	assert count[f64]([]) == 0

	assert count[int]([1, 2]) == 2
	assert count[int]([]int{}) == 0
