Introduction: count unique error

[aozgaa]

Similar to the previous issue, I see an error trying to count unique combinations:

> k
l2020.12.20 7GB 6core (c)shakti 2.0
 n:10000                     / n data points
  s:`a`b`c                    / data for symbols a, b, and c
  q:+s!(-1+n?3;-1+n?3;-1+n?3) / table of returns (-1,0,1) for each symbol
 #'=+(+q)[]                  / count each unique a/b/c combination
fky
#'=+(+q)[]                  / count each unique a/b/c combination

Hi Arthur.

Unfortunately group on list is currently not working. I expect it'll come back soon so generally leave the doc out-of-sync to the language. I'll leave this error open until it's fixed. If that doesn't happen soon then I'll modify the doc.

=1 2 3 1 2 1 / will work
=(1 2;1 2; 1 3) / not yet implement (NYI)
