Pre-SIP: A Syntax for Collection Literals

[tarsa]

between

@odersky

  [[1, 0, 0],
   [0, 1, 0],
   [0, 0, 1]]

and

@odersky

  Vector(
    Vector(1, 0, 0),
    Vector(0, 1, 0),
    Vector(0, 0, 1))

there could be:

val v = Vector // or alternatively you could do import with renaming
val matrix = v(
  v(1, 0, 0),
  v(0, 1, 0),
  v(0, 0, 1)
)

it works already for scala 2 and scala 3: Scastie - An interactive playground for Scala. and it has majority of the conciseness advantages
