1+2+3+4 = 10.
sum(4) = 6.
ocaml-sum(4) = 10.

:)

ruby: time -p ruby sum.rb 
499999500000
real    11.96
user    11.35
sys      0.00

ocaml1: time -p ./sum1
500000500000
real    19.19
user    17.79
sys      0.04

ocaml2: time -p ./sum2 
500000500000
real     3.89
user     3.62
sys      0.00

(check other mail for what is sum1/2)
