          Issue ID: 24890
           Summary: spec/arrays.dd should mention comparison and warn
                    about dangling .ptr
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: dlang.org
          Assignee: nobody at puremagic.com
          Reporter: nick at geany.org

Although array comparison is defined in expression.dd, arrays.dd should discuss
the difference between equality and `is` identity.

arrays.dd should also make it clear why `.ptr` is not @safe.

PR incoming.
