True, for Java and Kotlin I use the debugger in IntelliJ like a REPL all the time. You can even evaluate arbitrary expressions, connect to running applications even applications running on another machine. It's not as powerful as a proper lisp repl as you cannot redefine functions or classes, but it is still very useful.
