Common Lisp

Common Lisp (CL) is a dialect of LISP that adds functional programming, object-oriented and procedural features but cuts down the language features from what was common in the 70's although not as severely as Scheme. It was originally instigated by the USA's department of defence in the early 1980's as LISP variants used by contractors were starting to become so diverse that porting of code between projects was becoming difficult. It has since become the most popular variant of the language but sometimes gets criticised for being rather large in comparison to Scheme.
