E.g.
{
FileReader theFile = FileReader("thing.txt"); // this opens the file

// do stuff
}

// The file is closed now

When theFile is initialized it opens thing.txt. When theFile falls out of scope, for any reason, its destructor is called which then closes the file.

C#, on the client side, is also similarly clean.

using(ForgotTheName theFile = new ForgotTheName("thing.txt")) {
// Do stuff
}

However you don't get any protection against leaving the file open if you don't actually write "using" while RAII doesn't require such effort.

I get why C++ style RAII wouldn't work (you don't control object lifetimes in managed code) but I kinda miss it.
