Peter Williams:
Are the () necessary on sort?
If you don't use () I think you call the slower, not flexible and buggy built-in sort. I think it's already deprecated. Maybe I am wrong...
PS Now I've found this I can go back and simplify all the code where I iterated over associative arrays in key order by getting the keys and the sorting them separately.
I don't fully understand. Bye, bearophile
