I see your point... you are doing bio informatics..so speed matters.. 
for me the things are a bit different...

But I guess that you'll agree with me that Scala pattern matching has a 
reasonable syntax. (Not necessarily talking about "How difficult is it 
from a compiler author's view)

object MatchTest2 extends Application {
   def matchTest(x: Any): Any = x match {
     case 1 => "one"
     case "two" => 2
     case y: Int => "scala.Int"
   }
   println(matchTest("two"))
}
