Eliding Trailing Commas

[SpiralOSS]

I'm of the opinion that most commas are just another form of semicolon.

I've been working with a hacked version of the compiler to get this functionality, but it's so much nicer; and I hope you think so too:

Player :: struct {
   color : Color
   name : string
}

Color :: enum {
  Red
  Blue
  Green
}

MAP_LINKS :: [?]([5]int) {
  { 0,  1,  2,  3, -1 }
  { 0,  0,  7,  8, 10 }
  { 0,  0,  7,  8, -1 }
}

p := Person {
  stats = {
    health = 7
  }
  name = "Bob"
}
