Stupid Scala trick of the week: scala> val a,b,c = 1 a: Int = 1 b: Int = 1 c: Int = 1 scala> You're welcome, Internets

@deanwampler what's super "fun" about that one is the RHS is evaluated for each assignment, not evaluated once and shared
@dridus @deanwampler e.g.
val a, b, c = Math.random
val d, e, f = buf.nextInt()
More useful than evaluating once and sharing, in my opinion!

@propensive@deanwampler@advancedxy yeah, and if you have a mutable thing on the RHS, makes more sense. I know from Enum.., val a,b=Value() -
@dridus@propensive@advancedxy I completely forgot about enumerations. Won't make that mistake again!! ;)

@propensive@deanwampler why I call it super "fun" is because it replicates side effects unobviously. course, whole thing is unobvious.Thanks. Twitter will use this to make your timeline better. UndoUndo

@propensive@dridus@deanwampler surprises 100% of users ... was this done specifically to support Enumeration? /cc@extempore2 -
@tpolecat@dridus@deanwampler@extempore2 It predates Paul... I don't remember ever being surprised by it, but I learnt it from Enum first. - Show replies
