addTwo :: Num a => a -> a -> a
Haskell's type-inference provides generalized typing that works for floats as well:
λ: addTwo 2.0 1.0
3.0
If you must provide your own typing, it seems you'll need to use let combined with multiline input (use :set +m to enable multiline input in GHC...
Is there a Java equivalent to C#'s 'yield' keyword?

Interface
Aviad's library has a cleaner interface - here's an example:
Iterable<Integer> it = new Yielder<Integer>() {
@Override protected void yieldNextCore() {

Why are my JavaScript function names clashing?
..."Me original.");
}
f();
Which explains what you're getting, you're overriding the function. More generally, multiple var declarations are allowed in JavaScript - var x = 3; var x = 5 is perfectly legal. In the new ECMAScript 6 standard, let statements forbid this.
