I'll speak up for Perl. I learntbit voluntarily in my own spare time and actually get a lot of delight out of the language. I like that it is very unrestrictive. The sigils make sense when you wrap your mind around them and you miss them in other languages. It is excellent at parsing text. I wrote a static site builder using Perl along with a very rudimentary templating system ( https://soft.thran.uk for the curious)…
> it is very unrestrictive That makes collaboration hard. The freedom I have in putting my thoughts into code, uninhibited by syntax, types and conventions makes it nearly impossible for others to understand and modify my work.
The perl coding team I was on made readability our #1 priority. We didn't use tricky or out of the ordinary syntax unless it was absolutely necessary (like unusual regex, etc), and in those cases we would document what was happening with comments and maybe a reference to the appropriate man page. We had a style guide, for a consistent look and feel. We paid attention to naming and commented blocks of code, so the reader would not need to run an interpreter in their head while skimming through the code. We'd seek feedback from each other. It worked out well. We had no problems reading our code.
We used the flexibility and expressiveness of perl to make our code more readable. We had the freedom to tailor the code to what we were doing, instead of the other way around.
