+/* DYNAMIC VARIABLES
+
+ These are variables whose values are generated anew each time they are
+ referenced. These are implemented using a pair of function pointers
+ in the struct variable: assign_func, which is called from bind_variable
+ and, if arrays are compiled into the shell, some of the functions in
+ arrayfunc.c, and dynamic_value, which is called from find_variable.
+
+ assign_func is called from bind_variable_internal, if
+ bind_variable_internal discovers that the variable being assigned to
+ has such a function. The function is called as
+ SHELL_VAR *temp = (*(entry->assign_func)) (entry, value, ind)
+ and the (SHELL_VAR *)temp is returned as the value of bind_variable. It
+ is usually ENTRY (self). IND is an index for an array variable, and
+ unused otherwise.
+
+ dynamic_value is called from find_variable_internal to return a `new'
+ value for the specified dynamic varible. If this function is NULL,
+ the variable is treated as a `normal' shell variable. If it is not,
+ however, then this function is called like this:
+ tempvar = (*(var->dynamic_value)) (var);
+
+ Sometimes `tempvar' will replace the value of `var'. Other times, the
+ shell will simply use the string value. Pretty object-oriented, huh?
+
+ Be warned, though: if you `unset' a special variable, it loses its
+ special meaning, even if you subsequently set it.
+
+ The special assignment code would probably have been better put in
+ subst.c: do_assignment_internal, in the same style as
+ stupidly_hack_special_variables, but I wanted the changes as
+ localized as possible. */
