Description

If something in a lisp program is not a number, string or parenthesis, then it probably is a symbol. It is just a name in a package (which is not entirely unlike a namespace). Symbols may have a global value and/or a lexical value or even no value at all. The value may be a simple value like a number or a string, or a more complex value like a function.

    :usage undefined )
