Looking at the language spec, X10 has no syntactic support for
deterministic finalization. The common example is file access,
like this C# code:
using (File myFile = File.Open("foo.txt"))
{
/* Do something with myFile */
}
Similar things can be done in C++:
{
File myFile("foo.txt");
/* Do something with myFile */
}
In both cases, the file is closed at the end of the block and the
programmer cannot forget to write myFile.close(). While this mistake is
relatively easy to spot, consider exceptions. Usually, the close() call
should be inside a finally block.
In Scala it is possible to implement this as a trait.
