I'm trying to do Ruby password input with the Highline gem and since I have the user input the password twice, I'd like to eliminate the duplication on the blocks I'm passing in. For example, a simple version of what I'm doing right now is:

Defining a method:
def ask(msg, &block) puts block.inspect end
This is how you should do it, clean again to verify: ", &foo)
You can also use the pound sign to assign a block to a variable when.

What is a good way of creating non-blocking methods in Scala? One way I can think of is to create a thread/actor and the method just send a message to the thread and returns. Is there a better way of creating a non-blocking method?

A => Future[B] = (a => Futures.future(f(a))) // normally blocks when called def sleepFor(seconds = asyncSleepFor(5) // now it does NOT block println("waiting...") // prints "waiting..." rightaway.

Also, you can't return 'null' in a void method :)
Personal method is debatable - personal preference....
And I really try to avoid lots of nested 'if' statements .
In my opinion, it's more clear.
I prefer method 1, the "early exit" approach.

In addition to using "die" as exception, you can also add another method:

As we have access modifiers for methods and constructors, do we have it for static blocks? if yes what is the significance?
Answer Snippets (Read the full thread at stackoverflow):
Access modifiers (loosely speaking) tell you what you can ... .
And you can't call the static blocks either, so it wouldn't make much sense.
I'm assuming you want to write any.
I don't think you can have an access modifier for static blocks.

From the Sun docs
Normally, you would put code to initialize an instance variable in a constructor.
There are two alternatives to using a constructor to initialize instance variables: initialize blocks and final methods.
I could understand the use of ...

This is especially useful if subclasses might want to reuse the initialization method.
The advantage is already described in the very same Sun tutorial you linked to:
A final method.

It compiles to a try/finally block with the Dispose() call in the finally section.
The using statement is syntactic sugar.
This in the Dispose method of your repository, if you've got one.

Whether the method is large or not? the other thing to look for in very protracted methods is whether recommends about 7 methods per class and no more lines in a method then can be viewed in a single as blocks.

Methods that contain exception-handling blocks are not inlined, thoughAccording to Eric Gunnerson , the method has to be small enough to fit into 32 bytes of IL.
