Probably it should work if we're using a "SortedRange".
int[] a = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];
auto p = assumeSorted(a);
assert(3 in p);
That could work. Currently, you need to use p.contains(3). opIn could be
added as a shortcut.
It only makes sense if you have it as a literal though, as p.contains(3)
isn't that bad to use:
assert(3 in [0, 1, 2, 3, 4, 5, 6, 7, 8, 9].assumeSorted);
