I got this far:
S=:2 2 2 3 4
L=:3 4 8 3 7
le2=: 13 :'(=x) ([: ": #)"_1 y'
S le2 L
|length error: le2
| S le2 L
|[-4] c:\users\owner\j801-user\temp\137.ijs
But missed the second _
le2=: 13 :'(=x) ([: ": #)"_1 _ y'
S le2 L
3 4 8
3
7
Then this woke me up.
5!:4 <'le2'
┌─ ]
│ ┌─ [:
│ ┌──────┼─ ":
──┼─ ~ ─── " ─┤ └─ #
│ └─ _1 _
│ ┌─ [:
└─────┼─ =
└─ [
Thanks, Linda

Try
le2=: 13 :'(=x) ([: ": #)"_ 1 _ y'
S le2 L
3 4 8
3
7
You need to review the ranks of u@v and [: u v . I used (":@#) b. 0 to
find the ranks I used above.
