> The documentation appears to be out of date in regards to casting chararrays.
> http://pig.apache.org/docs/r0.7.0/piglatin_ref2.html#Cast+Operators lists chararray as being uncastable to anything else.
> This isn't the case since PIG-893 
> grunt> x = load 'tmp/numbers' as (a:chararray, b:chararray);
> grunt> y = foreach x generate ((long) b) + 1;               
> grunt> z = foreach y generate (chararray) $0;               
> grunt> dump y
> (2L)
