Milind Bhandarkar commented on PIG-796:

So, can we live with the classcastexception generated by the front end ? I 
recall reading somewhere that pigs do what they are told. If they are told to 
do things that are even impossible for humans to comprehend, i.e. somehow 
interpret a byte array to be an integer, and then to convert them to strings, 
how would they cope up ?

IMHO, eliminating such implicit casts would reduce complexity of pig, and would 
fit in the pig philosphy. But that means being able to convert everything to a 
chararray at most. If someone request a chararray cast of a bytearray, give 
them a hex representation, and have them write a UDF to convert hex string to 
string (i.e. toInt('0x'+myvalue) in the above code.)

thoughts ?
