Update Functions chapter of Lisp manual; document closures.
* doc/emacs/functions.texi (What Is a Function): Add closures. Mention
"return value" terminology. Add xref for command-execute. Remove
unused "keystroke command" terminology.
(Lambda Expressions): Give a different example than in the
following subsection. Add xref to Anonymous Functions.
(Function Documentation): Remove gratuitous markup.
(Function Names): Move introductory text to `What Is a Function'.
(Defining Functions): Fix defun argument spec.
(Anonymous Functions): Document lambda macro explicitly. Mention
effects on lexical binding.
(Function Cells): Downplay direct usage of fset.
(Closures): New node.
(Inline Functions): Remove "open-code" terminology.
(Declaring Functions): Minor tweak; .m is not C code.
* doc/emacs/variables.texi (Variables): Don't refer to "global value".
(Local Variables, Void Variables): Copyedits.
(Lexical Binding): Minor clarification of example.
(File Local Variables): Mention :safe and :risky defcustom args.
(Lexical Binding): Add xref to Closures node.

The `lexical-binding' variable lets code use lexical scoping for local variables. It is typically set via a file-local variable in the first line of the file, in which case it applies to all the code in that file. - ++++ *** `eval' takes a new optional argument `lexical' to choose the new lexical binding instead of the old dynamic binding mode. - ++++ *** Lexically scoped interpreted functions are represented with a new form of function value which looks like (closure ENV ARGS &rest BODY). *** New macro `letrec' to define recursive local functions. - ++++ *** New function `special-variable-p' to check whether a variable is declared as dynamically bound. |
