RFE: Introduce Decorated Class

How about a refactoring that will create a decorated class based on an existing supplied interface/class :

for example:

Id like to make a decorated Statement :

public class MyStatement implements Statement
{
private Statement statement;

public ResultSet executeQuery()
{
return statement.executeQuery();
}
...
...
}

This could easily be automated - as it is now, its a pain in the neck, especially when IDEA can already create all the interface methods, but it creates them with "default" return values - it woiuld be nice if the "implement interface" refactoring could be told to delegate all calls to the data member.
