What are the common challenges Clojure programmers face when integrating with existing systems?

Clojure programmers often encounter challenges when integrating with legacy systems, particularly those built in Java or other object-oriented languages. Navigating interoperability between functional and object-oriented paradigms can require extra attention to detail and thorough testing. Additionally, managing dependencies and ensuring compatibility with existing build tools and deployment processes are frequent considerations. Collaborating closely with teams familiar with the legacy stack and leveraging Clojure's robust Java interoperability features can help ease the transition.
