Common Lisp Review
The programmable programming language.
Ranked in these QuestionsQuestion Ranking
Pro Very Powerful REPL with SLIME
SLIME (Superior Lisp Interaction Mode for Emacs).
Pro Carefully designed for interactive use
Almost all aspects of the language are designed with interactive/repl use in mind.
Pro Condition/restart system
It is easy to recover from errors. Error resolution can be determined by the user at the REPL.
Pro Image based runtime
The state of the program may be saved and reloaded as an image, supporting safer modification of the running program. New code may be compiled into the image as the program runs, while late binding ensures that symbol redefinitions take effect throughout the program.
Pro Almost as fast as, or faster than, C
Some compilers such as SBCL can be faster than C or other low-level languages, and most compilers can generate fast native code.
