   It seems to me that the problems of having foo(NULL) be correct on
whatever machine you are working on could be taken care of by 
having pointer arguements aways be type coerced into whatever the
largest pointer type is on the machine (in cases presented to
me that is char *).  This could be done as part of the language
definition just as the float parameter are typed coerced into
doubles.  This assumes there is some bound on pointer type sizes
though.  Any comments?
