The pi_over_4 method I posted earlier is a good one. You can't
manipulate the _future_ result of that as if it were a number, because
(among other things) it never returns. Need a lazy functional language
for that kind of thing. (If that even suffices....)

_Maybe_ you could write a futures library and implement the pi_over_4
formula within that in some kind of useful way, but idunno.... I kind
of think you need laziness built into the core language for something
like that to be useful.
