- gnu.mapping.PropertySet
- - gnu.mapping.Procedure

All Implemented Interfaces:

Inlineable, Named
```
public class CallCC
extends MethodProc
implements Inlineable
```
Implement the Scheme standard function "call-with-current-continuation". This is a restricted version, that only works for escape-like applications.

    Description copied from class: Procedure
    
    Return minArgs()|(maxArgs<<12). We use a single virtual function to reduce the number of methods in the system, as well as the number of virtual method table entries. We shift by 12 so the number can normally be represented using a sipush instruction, without requiring a constant pool entry.
