Hi!
I was just surprised when realized, that this code compiles and
runs:

auto foo = TypeTuple!(foo,bar);
writeln(typeid(typeof(foo)));
writeln(foo);
}

Well, yes and no, not really. It's a bit magical. In your case,
it's assigned to an auto variable, and that variable gets that type.

I am trying to get members of a class via pointer to Object.
I know how to iterate over members when type is known at compile

int x, y;
}
Object o = new Foo();

exhibit any undefined
behavior if called by a safe function. Generally, trusted
functions should be kept

You have to qualify where the function comes from. One way to do

I was referring to the COM server support stuff in the Juno

I think you've hit bug city in the associative array
implementation. The this in there doesn't seem to point at
anything meaningful. This is probably worthy of a bug report.
A potential workaround is to store pointers to your structs in
the associative array, that way you can set them up

And I'd like to call a function like :

But this (of course) doesn't work. Is there a simple and nice way
to do this ? (I'm sure there is ;-))
