in thread Philosophical question about testing
This is why modules and subs arent talked about much
Modules and subs are talked about all the time by perl programmers who have half a clue about what they're doing.
If you push a block of code off into a sub inside a module, among other things you'll discover that it's much easier to write tests for it, and once you've got tests for it, it's much easier to re-write it as you describe (though reducing line count is hardly ever the first priority).
