I've been using it for several years now, and have posted about the setup several times. I absolutely love it.
Note that they have an excellent Open Source licensing program. This program if you qualify gives you a yearly-renewable license whereby you can use the professional version of every single one of their products. I've had this license for several years as well. I frequently use IDEA, PyCharm, CLion (and Rider, solely for the development of berrybrew), and Datagrip for databases.
The company itself is very nice to deal with (as I have to at least once per year for my license renewal).
As far as Perl, I concur that kudos goes out to Alexandr for sure. He even made things so that you can select berrybrew Perls as the SDK ;)
Also check out Devel::Camelcadedb, which affords you full Perl debugging support from within the UI.
Update: Oh, yeah... forgot to mention that the IDE also has a Vim plugin, so you can use a real editor inside of the IDE :P
