Can you define extensional vs. intentional programming?

How can I access a function if I know what it is supposed to do, and
nothing else?  That is our goal, to provide access to functions based on
what they are defined to do.  Functions don't need names if they have full
descriptions of their behavior that can be accessed and understood by
other programs. (I won't address extensional or intentional until you
define it)
