This is underrated. I know it sounds unprofessional, but funness is also the reason Basecamp and Ruby on Rails was built in Ruby. Rails dominated web dev in the 2010s and tons of super successful startups were built on it. So while many folks like to scoff at engineers "playing with toys", a lot of good things we have now used to be toys (edit: Linux is another good example of this)

I think that captures perfectly! I've actually written about that sentiment in the past [1]. The tricky thing with a very "fun" language is that you assume that you can solve everything with it. You end up writing a lot of code, when, in the end, no code would have been an acceptable solution.
