I agree with this. Easy to change often means good tests too. I worked in Perl. Yes it has a reputation for being hard to read, but that was not the problem. O

I agree with this. Easy to change often means good tests too. I worked in Perl. Yes it has a reputation for being hard to read, but that was not the problem. Our scripting was pretty basic and easy to read. It's the loose typing, the runtime evals, the lack of strict function parameters, no real IDE, “Only perl can parse Perl” - the fact you can load a module from a network share at runtime, import it, and call a function, based on a certain run flag - and so on. Refactoring was always a mine field and there was a lot I wanted to do in my old job but could not justify it due to the risk.
