Subject: [Caml-list] about optionnal argument ?
I wonder why optionnal argument are implemented through the option type instead 
of giving a defauklt value ?

Obviously the type should carry the default value which should be a closed 
constant (like None, 0, 0.0, [1;2;3], etc ...) but this would preserve the 
possibility of using optionnal arguments and unboxed int or float arguments
and it will save the None/Some test !
