Yes, since it's not documented anywhere it would just be tidying up to
delete it.

Subject: Re: [Jprogramming] What does gerund^:n do?
I am not eager to implement any new feature: it requires changes to
tests, documentation, dissect & lint. Plus, if you get it wrong you
have to live forever with your mistake. I will always listen to
proposals, though.

I think there are good cases for `:n to work for more n.
and if gerund y is to do something, it should be through `:n , though an
implied `:6 might be considered.
^:_1 should produce inverses and only inverses imo, and ^:n should do the same
as ^:v (where n is result of v y)
However, one use for this is to check that both gerund items are verbs, and
there are only 2. (errors if non verb is either of gerunds) but its not
graceful and doesn't recover with `::`
Now, if you are excited about implementing gerund^:n to do something, I can
think harder about something useful. But treating it as a typo is at first
thought, an improvement, and whatever I could come up with, some would still
prefer it be treated as a typo.

Yes. And it does the same for the dyadic case.
I wonder why this was done; and whether this or anything else should be
done in this case.

it applies the first verb. ignoring 2nd, and if there are more length error.
Hard to see usefulness, and if there was some, v0`v1`...vn^:n should behave
like v0^:n
Though, I'm fine with error.

+`*`- i.5
is simply an execution of dyad i., looking up 5 in the boxed list.
+`*:^:_1 i.5
0 1 2 3 4
seems to result in y
gerund not length 2 is a length error?
other n seem to be domain errors including 0
Now you're getting warm. The first statement is false, the other two
are true.

I'm ok with making this an error, rather than "improving" functionality to do something
"powerful"

No. All I see are domain errors when you try gerund^:n . The question
is, For what values of gerund and n does gerund^:n not fail, and what
does it do then?
(I already know the answer because I'm looking at the source code,
wondering whether this is functionality we ought to keep)

For certain gerunds and certain n,
gerund^:n
does not produce an error. What does it do?
