Consider a frozen object with unique properties that performs calculations that you wish to cache the results of.
Where would you recommend caching the results?
The object itself is frozen, so I can't store anything there.
There are no guarantees about how long it will stick around. As such, I can't use a thread-local hash map because it would retain strong references.
Is there a weak map implementation that could at least cache per-thread?

In 1.3.20 there will be MutableData, recently merged into maser:

I think that should only be used for exceptional cases though.
