No, `canFind` and `among` search for a given value in a range.
`in` checks if a given key exists and returns a pointer to the
associated data (not a pointer to the matching key). This is why
Phobos SortedRange does not implement opIn even though it would
be sub-linear. Dennis is right that conceptually a key for an
array is an index. An array element value is the data associated
with an index.
