You may want to use the sbclrc.sample with sbcl. Todo so you need to copy it to $HOME/.sbclrc or /etc/sbclrc if you want it system wide. This sbclrc provides an AllegroCL style Read-Eval-Print Loop for SBCL. An AllegroCL style inspector is integrated and handles fasl recompilation automatically for ASDF-based systems (for more details see the sbcl info 2.3.2 FASL)
