```
public class ReturnClausePush
extends TuplePush
```
The class represents the final stage in a push-mode tuple pipeline. The previous stages have stored the values corresponding to the current tuple in local variables on the stack; all that remains is to evaluate the return expression (with reference to these variables) and send the results to the current receiver.
