Because you mentioned canFind, I think you want the semantics
to be "is there an element with this value." If so, it would
be confusing to use the same operator for two different
things: For associative arrays, it means "is there an element
accessible with this key."
Does it? I always viewed it as "is this value in list of keys"
Array keys are the element index..
So essentially:
int[int] c1;
int[] c2 = new int[4];
c1[3] = 10;
c2[3] = 10;
assert(3 in c1); // true
assert(3 in c2); // what should this do?

If in were to mean "is this value in list of keys" then to be
consistent:
3 in c2 == 3 < c2.length
