Who else thinks that this is a very badly constructed bug/issue report? This should be made into a proper report (clear and info-complete), or removed. -- Bruno Medeiros - CS/E student http://www.prowiki.org/wiki4d/wiki.cgi?BrunoMedeiros#D

It might be the case that you understood it, but it still was very badly constructed: The title/summary: "Improve error message." This is clearly an terrible summary, it is awfully generic and non-specific (!) . (What error message?) The description: The description doesn't mention what causes the error, either with a textual explanation or with a code example. Derek, you understood it because surely you have seen it before, but I haven't, and so, if it wasn't for Deewiant example I (and anybody else in my situation) would not be able to figure out what the error was about at all (!) . The categorization: This is not a bug, it is a feature request. So perhaps it should have been filed under Severity:"Enhancement". -- Bruno Medeiros - CS/E student http://www.prowiki.org/wiki4d/wiki.cgi?BrunoMedeiros#D

------- Comment #1 from deewiant gmail.com  2006-06-18 10:09 -------
To show the issue more clearly:

--
class Foo { abstract void foo(); }
class Bar : Foo {}

void main() {
        Bar bar = new Bar();
}
--

The code fails with "cannot create instance of abstract class Bar". What is
being asked for is an error message which would, in this instance, clarify that
the reason the instantiation fails is that the method foo() is unimplemented in
Bar.

I think this is an important usability/productivity issue. Althought I don't
know the internals of the DMD compiler, I would expect the compiler to know
what is missing before deciding it can't create an instance. Therefore it
should be a simple matter to add that information to the error message.

In addition, I think this gives DMD, and hence the D language, a feeling of
incompleteness. Something which may be a hinderance to wider usage.

// __DSTRESS_ELINE__ 19

Why line 19?  Why not 16, where the abstract method is declared?

(In reply to comment #4)
 // __DSTRESS_ELINE__ 19
 
 Why line 19?  Why not 16, where the abstract method is declared?

I'd prefer both: 16 to indicate *which* abstract method isn't declared, and 19 to indicate *where* it isn't declared. --
