Support the visitor pattern.
For any implementation this should look like
C++:
v.visit( *this );
Python:
v.visit( self)
v | A visitor that visits this node. |

Generate a clone of this node.
Make sure that the clone does not contain any information which is generated in prepare and context related. Ownership is transferred to the caller.
