I hadn't before, but I have now.  Cool stuff.  I once wrote a
continued-fraction package with the something of the same flavour (since
overtaken by David Lester's work, which to my deep sadness remains
unpublished to this day).   

Your code clearly belongs in the nofib suite, as a splendid way to
consume compute cycles and test compilers.  Do send me a Main.hs to
compute pi, with a changeable runtime (presumably just adjust 'take').
