Just to mention one: renaming a function in CL code still requires regexp search whilc in Eclipse this is painfully simple.
No, it doesn't necessarily require regexp searched. Look at `C-c <' and the submenu entry SLIME -> Cross Reference.
I'm not sure if you meant that I shall list all references to the given function and I should manually edit all the listed files from that list?
It might be less time consuming and error prone as running a regexp search and replace but hey it's still very far from what eclipse does with renaming.
