    @laimis: Sure. I found that if you set file to null before entering the using's scope
and then, inside it, change it to reference a File object, it does not dispose the resources
correctly (namely, it does not close the file we are opening). I did an isolated test to reproduce
it (constructed a dummy IDisposable object and used the using instruction in the same way),
and it also failed. I am no C# expert, so I wasn't completely sure why this happened. Nevertheless,
it is reasonable that if you change the reference of the variable inside the using's scope,
bad things could happen.
