perl 4 still has the big global switch-based interpreter without the optree and optimizations on it. Ditch that. 5.6 is fast and almost never wrong compared to 5.14. With higher perls it is even much easier to get wrong results, because of more unexpected magic happening behind, more dependency bloat and less experienced hackers working on it. Module::Build is e.g. a prime example, where a native make replacement never got to the level of a make replacement, though it should have been possible with ~200 lines to get dependency handling in perl. This module still forces maintainers to drop 5.6. -- Reini Urban http://cpanel.net/ http://www.perl-compiler.org/
