This was meant as a boolean parameter. Would it make sense to have

enum boolean {
	false,
	true
};

or similar in some central place?

Note that an earlier version took a function pointer, and you could pass stdlib's free() in the common case, or a special free routine for nested entry structures, or NULL to do the cleanup yourself.
