--- Proposal ---
The proposal is to add weak reference functionality based on
`unstd.memory.weakref`. It can be placed e.g. in `core.memory`.
Source code:

Bikeshed: I'd use "lock()" instead of "@property target()" based on
precedence in the form of C++'s weak_ptr, but in general that should be
a very valuable (and long overdue) addition.
Just to reassure, the following race-condition doesn't exist, right? It
looks like "GC.addRoot()" makes guarantees by taking the GC lock or
something similar?

thread1: GC collection | | run finalizer |
thread2: paused | lock weak ref | | access object
