What would a general "find the index of the value x in the array y" verb
named fixv look like?
It would work like this:
] p=.3 4 5$?6

This is related to the question I asked several days ago,
http://jsoftware.com/pipermail/programming/2023-December/062994.html
My suggestion would be
8 (($@])#:[i.~,@]) A
1 3
Although you might want to an alternative behavior when there are
multiple matches.

8 ($@] #: [ I.@:= ,@]) A
1 3
8 (4 $. $.@:= ) A
1 3
Note that both of these results are rank 2.
