Instance Garbage Dump |
| 22 |
|
| 23 |
This is a resting place for un-needed instances. They may be stored in |
| 24 |
the dump in case they are needed later on. Only pure instance should |
| 25 |
be stored in the dump, and the dumping procedure is responsible for |
| 26 |
making sure that the instance it "pure", and unconnected to anything |
| 27 |
else. Typically, these restrictions are only met by atoms. |
