IMO the role of @ is essential and by removing it you amputate J.
How would you form trains equivalent to
(i.2 1)<@|: i.2 3
+---+-----+
|0 3|0 1 2|
|1 4|3 4 5|
|2 5| |
+---+-----+
(i.2 3)<@# 2 3 4
+-----+-----------------------+
|3 4 4|2 2 2 3 3 3 3 4 4 4 4 4|
+-----+-----------------------+
(1+ i.2 1)<@{.i.2 3 4
+---------+-----------+
|0 1 2 3| 0 1 2 3|
|4 5 6 7| 4 5 6 7|
|8 9 10 11| 8 9 10 11|
| | |
| |12 13 14 15|
| |16 17 18 19|
| |20 21 22 23|
+---------+-----------+
