In a different language that uses whitespace:

proc blank_map*:void =
 mines_placed = 0
 row8 = newseq[uint8](width); game_map = newseq[row8](height)
 row16 = newseq[int16](width); sum_map = newseq[row16](height)
 rowChar = newseq[char](width); state_map = newseq[rowChar](height)
 for h in 0.uint8..<height:
  game_map[h] = row8; sum_map[h] = row16
  state_map[h] = rowChar

I'm allowed to do it, it's allowed

(I don't use it a lot and I'm sure many dislike this because longer lines especially if they have less display width for whatever reason)
