The attached file, when compiled under the Mono C# compiler version 220.127.116.11, produces the following output:
While the result indeed mimics .NET's behaviour it is clear that there was a design error (at least according to people on SO), since it is expected for closures in that case to enclose on _different_ variables. Microsoft has recently changed the implementation of foreach and the behaviour is no longer perplexing in VS11.
I do understand that patching foreach might break some backward compatibility in theory, but in practice I can't honestly find a usecase for this (e.g.: when you need all of your closures to be enclosed on one variable with the last value).
Please pardon my English as I am not a native speaker.
