What is cl-global-vars
cl-global-vars is:
In Common Lisp, a special variable that is never dynamically bound typically serves as a stand-in for a global variable. This library provides true global variables that are implemented by some compilers. An attempt to rebind a global variable properly results in a compiler error. That is, a global variable cannot be dynamically bound.
Global variables therefore allow one to communicate an intended usage that differs from special variables. Global variables are also more efficient than special variables, especially in the presence of threads.
