Don't expect this to be fixed in J804. There are many small interpreter
bugs and no organized effort to repair them AFAIK.
This bug is similar to the previously-noted bug #86 which was that the
result was atomic rather than a list for equal Boolean values.
On my system, which is J32, /:~1 is 0.

So the fix may already be in process.
The versions that I have found with the issue are:
j602/2008-03-03/16:45 which is not surprising since it is not a current version
and
j803/2014-10-19-11:11:11 in the jhs environment on my mac, which is certainly
more current, although the whisperings suggest j804 may not be far off.

Subject: [Jprogramming] Results of 1/:1
Just spotted a question on stack overflow from Zhe Hu about the behaviour of
1/:1
http://stackoverflow.com/questions/29580291/j-sort-function-1-1-returns-0
2/:2 NB. expected result
2
1/:1 NB. expected 1 as the result
0
Also,
#$ 2 /: 2 NB. result is list as expected
1
#$ 1 /: 1 NB. result is atom, not a list as expected
0
I don't see the reasons that 1/:1 would return the atom 0 as a result, but that
does not mean there one does not exist. :)
Cheers, bob
