Asserion failure: 'structsize >= 8' on line 412 in file 'glue.c'

We can't write a derived class before its super one. Is this intentional? If it is, it seems very strange, doesn't it? Has this been reported already?

It is intentional, but you should have gotten a diagnostic rather than the assert notice.

You wrote that the D source is interpreted as a whole. This looks like an
exception. (And you hate exception, don't you?)
I know that there is no need for this to change: nobody is writing a base
class after a derived one. But IMHO this shouldn't be forbidden.

Yeah, I hate exceptions. But there did turn out to be some chicken-and-egg problems.
