-\strong{Programmer's note:} a ``\code{def}'' form executed inside a

-description of the new semantics.
+\strong{Programmer's note:} Functions are first-class objects. A
+``\code{def}'' form executed inside a function definition defines a

+used in the nested function can access the local variables of the
+function containing the def. See section \ref{naming} for details.
