Soft/weak references?

[Robert Fraser]

Hi all,

In Java, there's the concept of a "soft" reference to garbage-collectable data. Basically, a soft reference is a refrence to data that can be collected once there are no more strong references to it. It's useful for implementing, say, caches bounded by actual usage and memory availability, rather than some arbitrary limit.

Out of curiosity, is there any way to emulate this with the D GC?

Thanks,
Fraser
