Scala Gems #3: Named Parameters
Just a quick one this time (it's easter holiday and the weather is simply too beautiful to waste time in front of a computer). Anyway, have a look at this constructor call:
MigrosEasterEgg(GREEN, BLUE)
Unless you're Swiss and just know that I'm referring to the "Extra" variant, wouldn't it be a lot less ambiguous to write
val aMigrosEgg = MigrosEasterEgg(dotColor = GREEN, bgColor = BLUE)
As of Scala 2.8 you can name your arguments. You can also leave out those which have default values, shuffle their order — or you can simply have another one of those little suckers:
val notAMigrosEgg = aMigrosEgg.copy(dotColor = PINK)
Happy easter everyone!
