Veering away from Geany, I use intelliJ with the Camelcade Perl5 plugin (available within intelliJ's plugin system), the Vim plugin, and Devel::Camelcadedb, which allows you to debug within the IDE. Works flawlessly, and the IDE allows you to run and debug code from within, and also has a built-in terminal window.

• install intelliJ
• install plugins from within the IDE
• install optional Devel::Camelcadedb
• open project
• set your preferred Perl SDK (ie. select a perl binary to use for the project, IDE warns you if one is not set, and it's as simple as a couple of clicks to config)
• write code, run code, debug code
• commit/push to your VCS from within the IDE

Configuration can be copied to other machines easily, and runs everywhere (I run it on all my systems, Unix and Windows, including my Raspberry Pis). The setup also works exactly the same with PyCharm, which allows me to seamlessly use the same IDE for both Perl and Python development on some of my development machines.
