Hi, GridFlow/PD supports:

[for] as jMax emulation :
  [for 0 3 1] produces 3 messages: 0, 1, 2

[@for] in scalar mode :
  [@for 0 3 1] produces 1 message, a Grid of size 3: 0 1 2

[@for] in vector mode :
  [@for {0 0} {4 3} {1 1}] produces 1 message, a Grid of size 4*3*2:
    (0,0) (0,1) (0,2)
    (1,0) (1,1) (1,2)
    (2,0) (2,1) (2,2)
    (3,0) (3,1) (3,2)

the latter can be chunked into individual messages using [@import] to
reframe the data and [@export_list] to produce a list per grid.
