           Summary: Add basic regression tests for the twice-each bug
           Product: Swift
           Version: 0.93
          Platform: PC
        OS/Version: Mac OS
            Status: ASSIGNED
          Severity: normal
          Priority: P1
         Component: SwiftScript language
        AssignedTo: dk0966 at cs.ship.edu
        ReportedBy: wilde at mcs.anl.gov


Tests were added for the symptom of this bug that caused the mapper problem -
the bugs original symptom.

We should also add simple regression tests that test the most basic aspect of
this bug directly: foreach iterations being done more than once.

Here are a few of the original tests.  These could be packaged under language. 
We should stress foreach() in various ways, with input arrays created in
various ways.

David: this is a good exercise for adding new tests to the test suite.
