See reader questions & answers on this topic! - Help others by sharing your knowledge #' is a macro-character which expands #'FOO to (FUNCTION FOO). Symbols in Lisp have two bindings, one for values and one for functions, allowing them to represent both variables and functions, depending on context. #'FOO accesses FOO's lexical function binding in a context where the value interpretation would normally occur. #' is also used to create lexical closures for lambda expressions. A lexical closure is a function which when invoked executes the body of the lambda-expression in the lexical environment within which the closure was created. See pp. 115-117 of CLtL2 for more details.
