Re^4: Spoiled by Perl (sorting sugar)

thanks! :)

ehm ... if I have an array with numbers and strings it will implicitly decide based on the type of $a and $b which comparison to apply?

I'm not sure if that's sufficient to handle different standards.

E.g. the telephone book in Germany has another sorting than the dictionaries.

It will decide for you if you don't explicitly direct it to do otherwise. By default, given a number and a string to compare, it will coerce the number to a string. But if both elements being compared are numbers it will compare them numerically. If you want to sort all numbers as strings, you must say so, eg by passing `~*` as the comparator. > I'm not sure if \sorting by codepoint is\ sufficient to handle different standards.
