I think what disturbs me about these sort of 'with' extensions, is method resolution. How do we decide which object and method 'append' applies to. That area of the language is already broken by complexity.

As I wrote, it has some pitfalls. In my blog I noted down the order of resolution, which is the way one would expect it to be in Java, analog to using inner classes. This is a variant using an instance initialization block (legal Java code):

String string = new StringBuilder() {{ append(person.getName()); if (person.isMarried()) { append("(married)"); } }}.toString();

I suspect that a reasonably complete solution in this area would not fit the definition of small, and would be the subject of much conflicting opinion. :(

As I, too, stated ;)
