mg updated GROOVY-8302:
-----------------------
       Priority: Trivial  (was: Major)
    Description:     (was: This proposal revisits the idea to change the semantics of the break, return, and continue keyword for closures that are used in a way that mimics classical Java block constructs such as if, for, or while.

Example 1:
{code}
// Iterate over all PERSON rows in the result set
sqe.forEachRow("select * from PERSON") { final row ->
  if(row.TAG == 0) { break } // Leave forEachRow loop
  if(row.TAG == 1) { return } // return from the method enclosing the forEachRow loop
  if(row.TAG == 2) { continue } // Move to next iteration in the forEachRow loop
}
{code}


Example 2:
{code}
// Encapsulate with statically imported helper method that catches exceptions and ignores them, if the passed parameter is true
execWithOptionalIgnoreErrors(ignoreErrorsQ) {
  final x = dangerousOperation() 
  if(x == 1) { return } // return from the enclosing method
  // Note: break & continue are not allowed here
}
{code})
    Component/s:     (was: Compiler)
        Summary: Delete me  (was: break/return/continue support in "Appended Block Closures")
