On the face of it, the warning is silly ("2+2 :  warning: addition: 
result 4 found by applying the rules of arithmetic"). I think the intent 
might have been to show the actual location of the file: I could see how 
it might be useful to capture that, if 'load' allowed 2 return parameters :

[x,f]=load('penny.mat')

where x is the dataset being read and f is the filename.

All output should be catchable : it's neat that you can do

s=pkg('list')

for i=1:length(s)   printf("%s: %s\n",s{i}.name,s{i}.description)   end

I thought there were instances where this was not the case (I seem to 
remember that pkg didn't always provide a way to capture the output), 
but I can't recall where I ran into it.


BTW, is there a way to cut through a cell array without a loop, like 
s{1:length(s)}.name?
