           Summary: Allow RandomCover to sample both w/ and w/o replacement.
           Product: D
           Version: 2.029
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: Phobos
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: dsimcha yahoo.com


Currently, RandomCover only allows sampling without replacement.  I have
created a modified version, located at
http://dsource.org/projects/scrapple/browser/trunk/rangeextra/randomcover.d ,
that also allows sampling a random access range with replacement as an infinite
range.  This is done by template overloading on w/ or w/o replacement.  

This version of RandomCover also fixes bug 2865 and, in the w/o replacement
version, replaces the bool[] with a BitArray for better space efficiency.

David, I'm reassigning this to you. I've never had a need for random cover with
replacement, but if you can collect enough evidence please make a pull request.
Thanks!
