⊣ Left

Two-argument form  See also one-argument form Stop

The function ⊣ (left) takes left and right arguments of any type, rank and shape. It discards the right argument, and passes the left argument through unchanged.

It can be used as a statement separator, where (unlike using ⋄ diamond) the actual expressions are evaluated in normal APL right-to-left order:

      x←1 2 3 ⊣ y←4 5 6 ⊣ z←7 8 9
      x
1 2 3
      y
4 5 6
      z
7 8 9
