C# - Using-blocks and asynchronous operations

I think that the using statement in C# is a really nice invention. It’s an excellent syntactic sugar for handling IDisposables in a correct fashion. I get the impression that it took a while for the community to make it part of their daily routine to use it and now, as we are coming there, there is a shift towards asynchronous programming that may render the using block useless (or at least temporarily so, I hope to see C# 5 handling this in conjunction with the await keyword).
