--- Comment #9 from Martin Nowak <code at dawg.eu> ---
If scoped isn't enough, you could use automem (~master or the next release) for
ref-counted classes.
http://code.dlang.org/packages/automem

import automem.ref_counted;

    auto gen = RefCounted!(Generator!int)({yield(42);});
    writeln(gen.front);
    gen.popFront;
    assert(gen.empty);
