In the early 2000s Perl was godsend. A dynamic language that helped solve a lot of problems very quickly. But as soon as projects got larger and/or others joined your codebase you realized it does not scale. For me that was the moment when I slowly migrated to Python. So for me Perl‘s syntax (&@!#%), the easter eggs in the language, and the thousands of ways to be able to write things, killed it. It was just not maintainable.
