That's not entirely a correct statement. The rule is:

You cannot capture variables outside of function scope when using the Function constructor. You can create closures, like this:

Code:
var myFunc = new Function("var a=0; return function () { return a; }");
Technically, this function creates a function that is a closure (it captures the variable "a").

Generally, it's considered poor practice to use the Function constructor to create new functions, though technically it's not wrong.
