There are two API variants for working with CSelf values that will make it easier to write methods using the new APIs:
1) GetCSelf() -- on the RexxMethodContext. This is just like the GetSelf() method that's already defined in the interface. This will return the same value that would be passed using the CSELF argument type.
2) ObjectToCSelfScoped() -- this returns the CSELF object using a starting method scope for hte lookup.
