public class Wrapper
extends polyglot.ast.Expr_c

A Wrapper wraps an Amb inside an AST node so that it can be insert in the AST. However, the tree must be visited by an UnwrapVisitor before it is returned from the parser, otherwise the other phases of the compiler will be unable to work with the tree!
