          Issue ID: 19129
           Summary: std.typecons.scoped crashes when used on classes that
                    have context
           Product: D
           Version: D2
          Hardware: All
               URL: http://dlang.org/
                OS: All
            Status: NEW
          Severity: major
          Priority: P3
         Component: phobos
          Assignee: nob...@puremagic.com
          Reporter: e...@weka.io

Example:

  int y;
  class C { this(int x) { y = x; } }
  import std.typecons: scoped;
  scoped!C(1); // crashes, as ctx.y segfaults when ctx remains null

scoped should probably reject classes that have a "this" member (that aren't
`static class`).
