Re^4: Accessing $a and $b of 'sort' across package boundaries

ah. That makes sense -- i figured it was something like that. So is there any difference in these two, assuming the long_strings_first is how you defined it (using $_[0] and $_1 directly)?

sort gs::long_strings_first @$raw_hash_keys_ar;
sort gs::long_strings_first($a,$b) @$raw_hash_keys_ar;

(first one seems better in appearence, but just curious if any techincal sort-magic difference)

Actually, `sort gs::long_strings_first($a,$b) @$raw_hash_keys_ar;` won't run. You mean `sort { gs::long_strings_first($a,$b) } @$raw_hash_keys_ar;` Like I said, I think there's a substantial difference in performance. Let's put it to the test: Read more...
