Variable Bindings
=================

These Lisp forms make bindings to variables and function names,
analogous to Lisp's built-in `let' form.

   Note: Modify Macros, for the `letf' and `letf*' forms which are
also related to variable bindings.

Dynamic Bindings

The `progv' form

Lexical Bindings

`lexical-let' and lexical closures

Function Bindings

`flet' and `labels'

Macro Bindings

`macrolet' and `symbol-macrolet'
