Scratch that. I *must* have the name of the unimplemented method. I'm pretty
sure I've precipitated a compiler error, since this code was working well in
March. Now I'm compiling with 0.95, it's giving me that rather clueless
response. I'm perfectly happy to have to hack a workaround, but I need
somewhere to start.

No need to scratch anything.  For the benefit of all of us, the compiler 
ought to indicate which method is unimplemented, causing the class to 
become abstract.  Borland C++ manages it without any trouble.

But to be honest, I don't see what was wrong with making D like Java in 
this respect - a class is abstract iff it is declared as abstract.

Just looking at the docs, abstract doesn't seem to be explained at all!

it isn't, as far as i can tell.  and i can't find any reference to abstract
classes, let alone an explanation of what the "abstract" keyword does.  i'm
happy that Matthew found a way to make classes abstract!  i was beginning to
wonder if it were possible..
