Reading documentation... Array, Algorithms, ... maybe I've been

array like this
int[] a = [77,66,55,44];
I want to do something like:
int i = a.find_value_returning_its_index(55);
assert(i==2)
I'm sure it's obvious but I'm not seeing it right now.
int i = a.countUntil!(v => v == 55);
assert(i == 2);
It might not be an obvious application of countUntil, but it's
listed at https://dlang.org/phobos/std_algorithm_searching.html
