Bag constants used in non foreach statements cause lexical errors
-----------------------------------------------------------------
Key: PIG-583
URL: https://issues.apache.org/jira/browse/PIG-583
Project: Pig
Issue Type: Bug
Components: grunt
Affects Versions: types_branch
Reporter: Santhosh Srinivasan
Priority: Minor
Fix For: types_branch
Use of bag constants in non-foreach statement cause lexical errors in Pig. The
root cause is the inability of grunt to distinguish between nested block and
bag constant in non-foreach statements.

grunt> a = load 'input';
grunt> b = filter a by ($0 eq {(1)});
