There needs to be a way in foreach to indicate "and all the rest of the fields"

Key: PIG-1693
URL: https://issues.apache.org/jira/browse/PIG-1693
Project: Pig
Issue Type: New Feature
Components: impl
Reporter: Alan Gates
A common use case we see in Pig is people have many columns in their data and
they only want to operate on a few of them. Consider for example if before
storing data with ten columns, the user wants to perform a cast on one column:
{code}
...
Z = foreach Y generate (int)firstcol, secondcol, thridcol, forthcol, fifthcol,
sixthcol, seventhcol, eigthcol, ninethcol, tenthcol;
store Z into 'output';
{code}
Obviously this only gets worse as the user has more columns. Ideally the above
could be transformed to something like:
{code}
...
Z = foreach Y generate (int)firstcol, "and all the rest";
store Z into 'output'
{code}
