Bonjour tout le monde,

je me retrouve très souvent dans le cas suivant en utilisant les options :

val myOpt: Option[A] = ...

myOpt match {
  case Some(a) => Some(anotherThing)
  case None => {
    logger.info("...")
    None
  }

}

J'aimerais pouvoir utiliser plus souvent myOpt.map() pour éviter la
verbosité du pattern matching, mais je vois pas comment faire pour, au
sein du map, appeler mon logger dans le cas du none.
Une idée ? Ne pas appeler le logger ne fait pas partie des idées qui
seront retenues ! :-)

Jérémy
