It's not just about having eval(), it's also about having tooling to exploit its capabilities. I'm currently learning OpenGL with CL, and if I make a change to my main loop, I just hit a few buttons to recompile it without interrupting anything. As soon as it's finished compiling my loop silently switches over to it and the output reflects the new version of the loop. I have a Discord bot written in CL. If I want to add a new command or feature, I write it, hit a few buttons, and it seamlessly integrates with my bot without interrupting anything it's doing. If I have a problem with a macro, I can hit a button to have it expand right there in my code, and when I see the problem I hit a button to unexpand it. The editor will even catch errors and ask what you want to do, without interfering with other threads, which has been very useful while developing my bot.
