Custom lookupis more concise than find and match Some

//custom lookup
def codeBits(table: CodeTable)(char: Char): List[Bit] = table match {
    case x :: xs => if (x. _1 == char) x._2 else codeBits(xs)(char)
  }

// using standard find and match Some options
def codeBits(table: CodeTable)(char: Char): List[Bit] = {
    val couple = table.find({case (c, _) => c == char})
    couple match { case Some((_ , bits)) => bits }
  }                                               /
