>Common Lisp is the same But the great thing about Lisps is that they can't get stuck in the past. For example, if, say, Python didn't have decorators and you wanted to add them in, you'd have to present the idea in a PEP, get approval from Guido, write some code, et cetera. In Common Lisp, you just write some reader macros and that's it[1]. If Python stopped being maintained, it would lag behind other languages, but the fact that the Common Lisp spec hasn't been updated since 1996 doesn't make it any less modern. A more relevant example: Lisp doesn't have hash table literals, which every "modern" language these days has, but those can also be added, trivially in less than fifty lines[2] of CL code, and suddenly Common Lisp is modern again.
