           Summary: Casting from a function pointer to a delegate
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: dlang.org
          Assignee: nob...@puremagic.com
          Reporter: por...@narod.ru

Please add the following features:

- explicit casting from a function pointer to the corresponding delegate (with
the obvious semantics)
- implicit casting from a function pointer to the corresponding delegate
- `cast(delegate) ...` that would also do this cast.

The state would be set to null by such casts.
