          Issue ID: 19902
           Summary: hasElaborateCopyConstructor doesn't know about copy
                    constructors
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: regression
          Priority: P1
         Component: phobos
          Assignee: nobody@puremagic.com
          Reporter: turkeyman@gmail.com

`hasElaborateCopyConstructor` in phobos (and also in druntime: core.internal.traits) needs to be updated to understand copy constructors.

There may be some others that need tweaking too?
