REPL hates "."s

Dear Scalarazzi,
Welcome to Scala version 2.9.0.1 (Java HotSpot(TM) 64-Bit Server VM, Java 1.6.0_29). Type in expressions to have them evaluated. Type :help for more information.
scala> val s1 = "my.string.has.dots.in.it" val s1 = "my.string.has.dots.in.it"s1: java.lang.String = my.string.has.dots.in.it
scala> s1.split( "." )s1.split( "." ) res0: Array[java.lang.String] = Array()
scala> val s2 = "my-string-has-dashes-in-it" val s2 = "my-string-has-dashes-in-it"s2: java.lang.String = my-string-has-dashes-in-it
scala> s2.split( "-" )s2.split( "-" ) res1: Array[java.lang.String] = Array(my, string, has, dashes, in, it)
scala> 
Best wishes,

Or using a char as delimiter:

scala> val s1 = "my.string.has.dots.in.it".split ('.')
s1: Array[String] = Array(my, string, has, dots, in, it)
