          Issue ID: 15263
           Summary: Cannot insert range into DList
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: major
          Priority: P1
         Component: phobos
          Assignee: nobody puremagic.com
          Reporter: ryan rcorre.net

import std.range, std.container;

unittest {
  auto r = iota(0,5);
  SList!int slist;
  DList!int dlist;

  slist.insert(r); // passes
  dlist.insert(r); // fails
}

You can insert a range into an SList, but not a DList.
