I created a little "Pimp my Library" pattern for that problem. Maybe it'll help you out.

import util.matching.Regex

object RegexUtils {
  class RichRegex(self: Regex) {
    def =~(s: String) = self.pattern.matcher(s).matches
  }
  implicit def regexToRichRegex(r: Regex) = new RichRegex(r)
}

Example of use

scala> import RegexUtils._
scala> """\w+""".r =~ "foo"
res12: Boolean = true
