The issue with nested structures is a good point. Another problem I noticed would be natural language like syntax sugar, which makes it harder to maintain your knowledge of the language if you don't use it regularly. I learned some perl long time ago during one project, and after I stopped working with the project, I also gradually stopped using perl for quick scripts, and settled on sed/grep/awk again for quick simple stuff, and python for the other tasks.
