Definitely. I consider myself somewhat of a PL polyglot. After you've gotten experience in the different semantic paradigms (functional, OOP, imperative, etc), I think it's relatively simple to pick up a new language. It's mostly just a matter of learning some surface syntax and the standard library functions ('how do I concat two lists?', etc). The hard part is when you encounter a language that has complicated semantics.
