What about a to_h method for arrays?  I mention this mainly for the
sake of symmetry with other to_* methods.  Then again, such a method
may violate some principle of design: it does seem slightly wrong for
Array to "know" how to generate a hash (whereas not strange for Hash
to know how to create itself from an array).
