It's been said before, no harm in repeating it here.

For associative arrays,

        X in A

means that there exists a Y for which

        A[X] == Y

According to the semantics that get proposed every time this is brought up, for
linear arrays, it would mean the reverse: there exists a Y for which

        A[Y] == X

This inconsistency might be undesirable from a generic programming POV.

Besides, if we're going to have an operator to check whether a specified
_value_ is in an array, shouldn't it be available for AAs as well?
