I dunno, you might have some sort of efficiency test and store the 
results in an array keyed to the names of the various tests and you want 
to see them in the order of best to worst.

I think that for the time being this works for me:


typeset -A array=( [1test_one]=123 [2test_two]=345 [3test_three]=111 
[4test_four]=5 )

echo "\nraw"
printf "\n%-20s %s" ${(kv)array}
echo "\n\nsorted on key"
printf "\n%-20s %s" ${(kv)array} | sort
echo "\nsorted on value"
printf "\n%-20s %s" ${(kv)array} | sort -k2
echo "\nsorted on value numerically"
printf "\n%-20s %s" ${(kv)array} | sort -k2g

output:


5 /aWorking/Zsh/Source/Wk 0 % . test2

raw # No recognizable order

1test_one            123
2test_two            345
4test_four           5
3test_three          111

sorted on key # If the array itself won't do it, then make 'sort' do it:

1test_one            123
2test_two            345
3test_three          111
4test_four           5

sorted on value # dictionary sort

3test_three          111
1test_one            123
2test_two            345
4test_four           5

sorted on value numerically # numeric sort

4test_four           5    # This isn't going anywhere.
3test_three          111
1test_one            123
2test_two            345  # Here's the winner, congratulations test_two 
team.

... so however much I think there should be a defined order to the way 
the arrays print, it seems easy enough to use other tools to do it.
