[I thought I had sent this yesterday, but today I find it in draft status]
Note that you can eliminate some of the parenthesis here, and some of
the quotation marks (though this does place a burden on the reader's
understanding of j syntax):
({{y`:6 nc`''}} ^: 9 +:`'') (`:6) 7
23
or
({{y`:6 nc`''}} ^: 9 +:`'') `:6 ]7
23
The final parentheses are essential (to force early verb evaluation).
