-Variables and functions defined locally to functions are only visible in the scope of the function where there were defined.  In the previous example, //fac// uses a local function //inner// that is only visible inside //fac// and its nested scopes, in the example //fac.inner.//
+This example also illustrates how a function can be made private by means of lexical scope. Variables and functions defined locally to functions are only visible in the scope of the function where there were defined. Note that local //inner// function is only visible inside the //fac// function and its nested scopes. Thus, calling //fac.inner(2,3)// will return a lookup failure error.
