A program that can generate, compile, and execute new code is nothing special in the Common Lisp world. One can build lambda expressions, invoke the compile function on them, and call the resulting compiled functions. One can even assign these functions to the symbol-function slot of symbols, allowing them to be called from pre-existing code that had been making calls to that function named by that symbol.

I know that no other language can match Lisp, but many languages can generate and execute new code, if they're interpreted. Compile, too, if they're JITted. They all require quite a bit of runtime support though.
