Interesting... but I dont understand... I thought that referential
transparence meant that once the answer to a function has been
calculated once, it will always be the same, and that the interpreter
can, and will, cache this answer?

So, if I call f( 20 ) once, for some, arbitrary, f, it will have to go
away and calculate f(20), but if I call it multiple times, it will
just return the value it already calculated?
