           Summary: 'in' not allowed in 'for' loop
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: objc
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: nicola@gcc.gnu.org


The current implementation of Objective-C fast enumeration does not allow a
variable to be named 'in' if used inside a 'for' loop.  For example (in c99):

int main (void)
{
  for (int in = 0; in < 10; in++)
    printf ("%d\n", in);

  return 0;
}

Since Objective-C is (or should be) a superset of C (as much as possible), the
previous snippet of code, which is valid C, should also compile with the
Objective-C compiler.

Thanks
