refcount() has been added to the language, which will return the number of references for a given object. If that object does not use reference counting, the result is zero.

This issue has been resolved.
It would be useful for custom garbage collection schemes + debugging such schemes if we could access he reference count of a datum with some method.
I know BYOND already internally stores this.

This has been brought up before. It's unfortunately not possible. The primary reason is that the very act of loading a value for the proc and putting it on the stack would distort the reference count. There are temporary vars inside of a proc that might hold refs, so those would also be relevant.

Screw it. It's in for 515.

I think even so people can take that in for account and still get a rough idea of how many references they have left to get rid of. A lovely feature
