This is what DMD 2.061alpha prints, it doesn't crash:

...\dmd2\src\phobos\std\range.d(603): Error: static assert

Nice. Thanks!

assertion failure with template instantiation of forward reference class

[comco]

When trying to compile this code:

import std.stdio;
class A;

class B(T) : T {
}

void main() {
writeln(typeid(B!A));
}

I get this error: Assertion failure: '!scope' on line 358 in file 
'toobj.c'.
Shouldn't it be more like: Error: class main.A unable to resolve 
forward reference in definition


Looks like a bug?
