Selfish Promotion: Jax

When I look at the following code:

Scanner scanner;
try {
    scanner = new Scanner(filename);
} catch (FileNotFoundException e) {
    throw new RuntimeException(e);
}
ArrayList lines = new ArrayList();
while (scanner.hasNextLine())
    lines.add(scanner.nextLine());

All I can think of is what a shame it is that I have to declare scanner before the try-catch block (and that the curlies are mandatory).

Here's the equivalent in my experimental programming language Jax:

Scanner scanner = try new Scanner(filename) 
                  catch (FileNotFoundException e) 
                      throw new RuntimeException(e);
ArrayList lines = new ArrayList();
while (scanner.hasNextLine())
    lines.add(scanner.nextLine());

That first line shows how try-catch blocks evaluate to an expression. Everyone should be thrilled about Jax so I have motivation to continue working on it!
