Is there any plans to make working signals in D?

If an array of weak references works this way, then it is also easily
implementable in the library. For thread safe weak references another
hook would be necessary though, as Soenke has pointed out.

My current approach is to use a /simplified/*) lock-free list.
Simplified because I make use of the way the GC works, so it is not
thread safe in general. The lazy approach would make this unnecessary.

Maybe I go for lazy, the more sophisticated solution can be implemented
later on if really deemed necessary.
