           Summary: Clean up old code for packed bit array support
           Product: D
           Version: 0.161
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: minor
          Priority: P3
         Component: Phobos
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: sean at f4.ca


Phobos still contains some code used for packed bit array processing, and it
should probably be cleaned up at some point.  Omitting the alias for "bit" in
the global object module generates these errors:

internal\arraycat.d(69): identifier 'bit' is not defined
internal\arraycat.d(117): identifier 'bit' is not defined
internal\arraycat.d(154): identifier 'bit' is not defined
internal\arraycat.d(170): identifier 'bit' is not defined

internal\adi.d(310): identifier 'bit' is not defined
internal\adi.d(356): identifier 'bit' is not defined

std\format.d(138): identifier 'bit' is not defined
