/**
    BOOL rv = @[@1, @2, @3].has(@2)
    // rv => YES

Short-hand for containsObject:. Provided because doing a map, then a
select and a few more chained dot-notations are commonly followed with
the need to then determine if a particular value is in the resulting
array, and then having to square bracket the whole chain is ugly.

We decided not to override any or find with the capability to take an
object rather than a block and instead add this method. Rest assured the
decision was careful. In the end has() seemed the choice that resulted in
the clearest code.

`has` was chosen over *contains* or *includes* because it is short and
clear.
