> In interactive mode (grunt shell), the type validation should be done as soon as a line of script is added .
> For example -
> {code}
> grunt> l = load 'x' as (a : chararray, b : int);
> -- no error when following statement is typed
> grunt> f = foreach l generate a + b;   
> -- errors only when explain/describe/dump/store is called 
> grunt> describe f;

> Another example-
> {code}
> grunt> l = load 'x' as (a : chararray, b : int);
> grunt> f = foreach l generate CONCAT(a,b);
> grunt> describe f;
