Dylan is a LISP -like language created at Apple as a scripting language. It is quite dynamic, like Lisp, has a syntax similar to C, and provides an object system similar to CLOS. Apple discontinued efforts to develop and deploy it. The parallels to Common Lisp are very strong as a number of the designers of Dylan were involved with CL standardization.
Folks at CMU are maintaining the Gwydion Dylan implementation for Linux and other Unix-like OSes; it can behave both as an interpreter as well as compiling into C code...
