One place that is somewhat painful for me is when dealing with interfaces and vars vs. getters/setters. Most of the time my interfaces use methods only, but there are occasions where it makes sense to toss a property in there. Since you can't have var in an interface, I find myself writing getters and setters. Small pain, but a pain.
Oh, another one. When you're extending the Cairngorm ServiceLocator. Back in the days before getService was deprecated, we used vars to represent the services, because that was simple. When we upgraded to getWebService, things broke because it uses describeType to find read/write accessors. Another place where it would be handy to have the auto-generation. (I know, could have changed their implementation, but wasn't as well-versed at the time).
