           Summary: Error messages refer to _dtor instead of ~this
           Product: D
           Version: 1.00
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Keywords: diagnostic
          Severity: minor
          Priority: P3
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: deewiant@gmail.com


class Foo { abstract ~this(); }

The above generates "function asdf.Foo._dtor non-virtual functions cannot be abstract". That should read "asdf.Foo.~this".

class Foo { auto ~this(); }

The above is similar: "function asdf.Foo._dtor functions cannot be const or auto". With const the behaviour is, of course, the same.

However, a leftover from before "scope" is the following:

class Foo { scope ~this(); }

This emits "function asdf.Foo._dtor functions cannot be const or auto" as well. This should say something about scope.

------- Comment #1 from clugdbug@yahoo.com.au  2009-04-01 09:47 -------
The 'scope' error has already been fixed for D2, but not for D1.

This simple patch changes  __dtor into ~this, by analogy to how it's done for constructors.

This seems to have been fixed for a while now...
