LISP

It's a slow shit interpreted language, doesn't have libraries, you have only recursion and stack overflow, doesn't have an {b.u.i.o ENTERPRISE-GRADE OBJECT-ORIENTED SYSTEM}, you can do just fact an fibs.
Why do you use it?

This troll is geting old. Most modern Lisp implementations are both natively compiled, fast, have enough libraries (although not all are well maintained), and "stack overflows" only happen if you're being stupid. My bet is you don't even know Lisp or used it for anything real.
