Hmm, this feature is used in Phobos in 
[std.signal](https://github.com/dlang/phobos/blob/master/std/signals.d#L259). Actually, this is how I found it, since I implemented the Signal functionality, but without garbage collection. It seems to me that this is an undocumented feature, rather than a bug.
