I target 5.10.1 mostly. This is for a project I started in the late 90's. It uses CGI::Application, which is less a framework and more a method lookup table converter of queries (although I built a path info convertor on top of that). It's still maintained, although before Covid, it was my livelihood.

About a quarter of a million lines of code, excluding the libraries I pull in. I'm mostly self-taught, they wouldn't even let me get a minor in Comp Sci, since I didn't have the math background (Needed Calculus, I completeled Algebra 2 in hs). Boneheaded Uni.

Raku: Second-system effect poster boy. Sensationally dysfunctional community. I think Pugs is what was actually really incredible and Audrey is probably one of the most intelligent people in... the World? Up for contention, but top 10.
