I don't understand all uses of the request but typeid() returns
a TypeInfo reference, which is about the actual type of an
object. The following change produces the expected output in
this case (except, it has the added module name):
void bar() { writeln(typeid(this).name); }
The output:
A
deneme.A
B
deneme.B
A
deneme.B

For something as simple as the name, yea, type id works. But for
something like iterating over UDA's or looking at
__traits(allMembers) or something like that, type id is not what
is needed.
