if you use SBCL, use rlwrap

maybe you scream "why ↑ key dont work on SBCL REPL"
i know your feeling
lisper may think lisp is great, but SBCL is f**ck

SBCL dont keep history, so use rlwrap.

$ brew install rlwrap

and, add this lines in .bashrc or like a that

alias lisp="rlwrap sbcl --load quicklisp.lisp"
