I am curious about several things in your second line, mostly the refactorability claim, though. Perl has great testing tools, and its community has embraced them wholeheartedly for a decade* . I find the ubiquity of TDD-like practices among Perl developers make refactoring a dream. * The very first Perl release in 1987 actually had a test harness which eventually grew into the modern TAP system, but the 'testing revolution' in the community dates to 2000 or so
