ExitExp

public ExitExp(Expression result,
               BlockExp block)

ExitExp
```
public ExitExp(BlockExp block)
```

Method Detail
- mustCompile
```
protected boolean mustCompile()
```
  Specified by:
  
  mustCompile in class Expression
- apply
```
public void apply(CallContext ctx)
           throws java.lang.Throwable
```
  Description copied from class: Expression
  
  Evaluate the expression. This is named apply rather than eval so it is compatible with the full-tail-call calling convention, and we can stash an Expression in CallContext's proc field. FIXME - are we making use of this?
  
  Overrides:
  
  apply in class Expression
  
  Throws:
  
  java.lang.Throwable
- compile
```
public void compile(Compilation comp,
                    Target target)
```
  Specified by:
  
  compile in class Expression
- deepCopy
```
protected Expression deepCopy(IdentityHashTable mapper)
```
  Overrides:
  
  deepCopy in class Expression
- visit
```
protected <R,D> R visit(ExpVisitor<R,D> visitor,
                              D d)
```
  Overrides:
  
  visit in class Expression
- visitChildren
```
protected <R,D> void visitChildren(ExpVisitor<R,D> visitor,
                                         D d)
```
  Overrides:
  
  visitChildren in class Expression
- print
```
public void print(gnu.kawa.io.OutPort out)
```
  Specified by:
  
  print in class Expression
- calculateType
```
protected Type calculateType()
```
  Overrides:
  
  calculateType in class Expression
