Hmmm.  There was recent discussion of block encryption...  Now if 
bitXor, and [ ]  could be expanded appropriately, maybe blocks could be 
encrypted and decrypted in parallel.  And with a slight improvement in 
binaryEncode and binaryDecode maybe variables in those can be arrays.

Maybe if array operation semantics were expanded to other operators, we 
might find more applications of array operators.  Such as encryption.

This should be good for ECB mode and for much or most of other modes.

I wonder where else array operators might be handy.
