<Berengal> One interesting aspect of callCC is that even though it's a time
traveller, you can't travel forward in time, because you don't
have a reference to it. You can however go *back* in time with a
reference to the *current* time, give yourself that reference
and jump to the point you are now from the past, which is as
close as makes no difference
<hatds> that didn't turn out so well in Back to the Future 2 if I
remember correctly
<Berengal> hatds: Ah, well, but my algorithm doesn't reach 88mph yet
<idnar> haha
* Berengal bolts on boosters
* idnar installs callCC in a blue police box
* Berengal thinks the blue police box /is/ callCC
<idnar> so the time vortex is just an infinite cascade of lambdas?
<Berengal> It's lambdas all the way down
