On the flipside, I was thinking of learning CL as a Julia developer and this post has somewhat discouraged me to do so. What can learning CL do for me apart from realising that S-expression syntax is superior?

For context, I very often find myself building small libraries from scratch to solve very specific scientific problems which is somewhat performance critical. Julia has worked very well for me for this, but I recognise that moving outside of your comfort zone is the best way to become a better programmer.
