The argument for gerund"n is this:
All partitioning modifiers (/. / ;.n etc,) support cyclic gerunds. The
anomalous case is " which is the most basic partitioning modifier of all.
It should have been defined to support cyclic gerunds.
The proposal is to put it right without breaking any code. m
the best solution I've seen,
isgerund =: 0:`(0 -.@e. 3 : ('y (5!:0)';'1')"0)@.(0 < L.) :: 0:
tests that each "box" can be passed to 5!:0 without error.

A noun need not be a gerund.

A gerund is a noun.
g=:+`-
g-:;:'+-'
1
I don't know if others have taken advantage of building gerunds as boxed
lists, but I have. Can gerunds have rank greater than 1? So far I haven't
found a use for that, but who knows?

J interpreter must know when a noun is a gerund, so is it possible to add a new
primitive to test for gerund? Or is there already J script to test for gerund?

I also thought that it would be unlikely to brake any existing code [0].
It was implemented as " and broke an important code I had written! That
is why it was reimplemented as ":: instead.

Oh, wait, I missed the cyclic part.
I still think it could be done differently. Why don't we have a cyclic
gerund invocation which does not involve " ?
For example, we could add an n value for g`:n which creates a rank _
verb which has an effective rank of -#$g
Anyways, I really don't like the i
"where n is not _"
That is a good idea. We tried trying to detect a gerund for any n but it
didn't make it past the standard library. Ignoring the gerund case for
rank _ might get further. I don't remember if I tested for stuff like
(<'const')"0. I will check that when I get a chance.

In other words, this seems to be the proposal:
G=: mean`''
G"0 i. 2
┌┐
│mean│
├┤
│mean│
└┘
mean=:+/%#
G"0 i.2
0 1
But we could already do this:
G`:6"0 i.2
0 1
Personally, I do not feel comfortable agreeing that saving three
characters is enough benefit for creating th
m"n with gerund m seems valuable to me.

I expect to make some more improvements to dyad u"n, and eventually to
rewrite the monad to match the dyad. My availability to work on this will
be intermittent for a while. The 8.06 code as is works, and fixes a
long-standing bug reported by Martin Neitzel.
I have suggested using m"n, where n i
IMO Clang does a good job here. And the following

*((volatile I*)0)=0; // scaf
I think jx provides useful facilities but some of them are
incompatible with J dictionary.

You can try removing the conditional statement enclosing that line, but
for now I would say the patch is broken under Clang. Since the rank code
was completely rewritten in J805 and J806 and ":: is based on the J804
rank with some unfinished updates Henry was working on, the real
solution is to
Yes, I use Clang and have -Werror -Wextra in CFLAGS.
Sometimes vs2013 is much less tolerant.

That looks like Henry's code taken from cr.c at some older version. It
compiles fine for me in GCC and Visual Studio 2013. It is in the
implementation of "::, which seems to be working in my tests, so that
code never gets hit. Are you using Clang? It's much less tolerant of
code like that.

*((I*)0)=0; // scaf
and I can not understand its intention, access to memory
address 0 should cause segfault.
