I've used SBCL regularly since the initial announcement, truly an excellent piece of software that only keeps getting better. Being able to sit back and watch bug fixes and performance improvements trickle in without having to deal with the usual torrent of new/deprecated features is a nice change from other languages. Using implementation-specific features is mostly frowned upon in the CL community, but SBCL is so rock-solid and readily available that I feel less and less motivated to deal with cross-implementation issues. Much like GHC in Haskell land. Keep it up!
