I've used Komodo IDE for many years. It's editor engine is the same engine used for Sublime Text so there is a lot of feature cross over in the editors. When I'm developing Perl code I pretty much never leave Komodo. It's debugger support is great and the IDE integrates well with test and coverage tools. Common revision control systems are well supported. And these days it is essentially free, although if you are doing a lot of script coding it was worth the price of admission even when it was a pay for product.
