A simple example touching on Implicits and Options much like C# extensions and F# Options

implicitsandoptions.scala

object Main {

	implicit class Converter(val s: String) {
		
		def MaybeInt: Option[Int] = {
			
			try {
				Some(s.toInt)
			}
			catch {
				case e: NumberFormatException => None
			}
		}

	}
	
	def main(args: Array[String]) {

		"123".MaybeInt match {
			case Some(x) => println(x)
			case None => println("not a number")
		}
	}
}
