.tupleof accesses an extra (unknown) member on nested classes.
The following example shows this bug on dmd 1.020 and 2.003, also gdc gives a similar result
--- main.d ---
import std.stdio;
class A
{
char name = 'A';
class B
{
char name = 'B';
}
}
void main()
{
class C
{
char name = 'C';
}
A a = new A;
a.B b = a.new B;
C c = new C;
writefln(a.tupleof); // prints: A
writefln(b.tupleof); // prints: B main.A
writefln(c.tupleof); // prints: C 0000
}

tupleof shouldn't be including hidden 'this' members.
PATCH: mtype.c, line 7138, TypeClass::dotExp()
if (ident == Id::tupleof)
{
/* Create a TupleExp
*/
e = e->semantic(sc); // do this before turning on noaccesscheck
Expressions *exps = new Expressions;
exps->reserve(sym->fields.dim);
for (size_t i = 0; i < sym->fields.dim; i++)
{ VarDeclaration *v = (VarDeclaration *)sym->fields.data[i];
+ // Don't include hidden 'this' pointer
+ if (v->isThisDeclaration())
+ continue;
Expression *fe = new DotVarExp(e->loc, e, v);
exps->push(fe);
}
e = new TupleExp(e->loc, exps);
sc = sc->push();
sc->noaccesscheck = 1;
e = e->semantic(sc);
sc->pop();
return e;
}
