Sorry, but language doesn't matter that much if the entire environment/stack is decent. If you are using overly "clever" features of the language, then you may be writing write-only code that has a high probability of tripping up new hires.
I see too many trying to reinvent the database or operating system in application code. Don't.
We have different definitions of clever. Using iterator combinators is pretty par for the course and sort of a minimum understanding I would expect anyone to have.
