I think I may have found another bug (n. 41) in DMD:

void main() {
    { class Foo {} }
    { class Foo {} }
}

It produces:
t.o:(.rodata+0x34): multiple definition of `_Dmain3Foo6__initZ'
t.o:(.rodata+0x0): first defined here
...

-------------------
Unrelated:
I may have found a bug in std.intrinsics too, shown by this code:

From the specs:

"A nested class is a class that is declared inside the scope of a function or another class."

It doesn't say a class can be local to a block of code.

Why don't you file them in bugzilla?
