12. def setup(code: (A) ⇒ Any): A

    

    Alternative syntax for applying some side effects on a value before returning it, without having to declare an intermediate variable.

    Alternative syntax for applying some side effects on a value before returning it, without having to declare an intermediate variable. Also, using setup confines the "setting-up" code in a separate code block which has more clarity and avoids polluting outer scope.

    Example:

    1. import javax.swing._
       // this entire expression returns the panel
       new JPanel().setup { p =>
         p.setEnabled(true)
         p.setSize(100, 100)
       }

13. macro def showAst: A

    

    Prints AST of the prefix in a compilation error.

    Prints AST of the prefix in a compilation error. Useful for debugging macros.

14. macro def showRawAst: A

    

    Prints raw AST of the prefix in a compilation error.

    Prints raw AST of the prefix in a compilation error. Useful for debugging macros.

22. def unboxedOpt[B](implicit unboxing: Unboxing[B, A]): commons.Opt[B]

    

    Converts a boxed primitive type into an Opt of its corresponding primitive type, converting null into Opt.Empty.

    Converts a boxed primitive type into an Opt of its corresponding primitive type, converting null into Opt.Empty. For example, calling .unboxedOpt on a java.lang.Integer will convert it to Opt[Int].

23. def |>[B](f: (A) ⇒ B): B

    

    The "pipe" operator.

    The "pipe" operator. Alternative syntax to apply a function on an argument. Useful for fluent expressions and avoiding intermediate variables.

    Example:

    1. someVeryLongExpression() |> (v => if(condition(v)) something(v) else somethingElse(v))
