The question has been answered already. The mathematical convention is
too important.
Thus minus - , divide %, less -. , element e. and by the way Matrix
divide % have the
conventional arguments and differ from the J rule:
"x are the control information - y are the data" as expressed in JfC.
But so far I have not seen the argument, why the sort /: and \: behave
different.
When writing code I quite often make mistakes here, so a good argument
would help to remember.
Thanks,
Markus

It seems that the Residue function should follow the same argument order as %
It does not seem consistent or intuitive for the arguments to be reversed.
What motivated this decision? I spent 5 minutes about to tear my hair out trying
to figure out the results I was getting from Residue.
7 % 2
3.5
2 | 7 NB. would be 7 | 2 if I were designing J :)

I'm sorry to ask what seem like such nitpicky little questions, but I got a
great answer regarding Passive, so perhaps I am just ignorant of some loftier
motivation for such argument calling conventions.
