Syntax for ?: requires parens in FOREACH
----------------------------------------

                 Key: PIG-394
                 URL: https://issues.apache.org/jira/browse/PIG-394
             Project: Pig
          Issue Type: Bug
          Components: grunt
    Affects Versions: 0.1.0
            Reporter: Ted Dunning



This fails

clean = FOREACH log {
    ev = eventType eq '/rate/video'?'none':eventType;
    GENERATE ev as event, 1 as cnt;
}


but this works

clean = FOREACH log {
    ev = (eventType eq '/rate/video'?'none':eventType);
    GENERATE ev as event, 1 as cnt;
}

The requirement for parens is bogus.  Also, this fails with very misleading messages:

clean = FOREACH log {
    ev = (eventType eq '/rate/video')?'none':eventType;
    GENERATE ev as event, 1 as cnt;
}

I think that the parser needs to be completely revamped to avoid this sort of strangeness.
