14:59:48pjbMidWit: there for when I run ./my-script the rc file is not loaded, so :testing is not in *features* so the main is called and the script exits with the returned status; but when I launch clisp and I (load "my-script") then :testing is in *features* and main and quit are not called. So I can call (main) at the REPL and debug it.
