Bringing Perl's (main) regex operators to [Scala] (just for fun)

StringExtensions.scala

implicit class StringExtensions(val _value: String) extends AnyVal {
  def =~(r: Regex): Boolean = _value match {
    case `r`()        => true
    case `r`(xs @ _*) => throw new IllegalArgumentException("Regex must not contain captures")
    case _            => false
  }

  def !~(r: Regex): Boolean = !(this =~ r)
}
