MAYBE

Problem:
 function(iszero(),0(),dummy,dummy2) -> true()
 function(iszero(),s(x),dummy,dummy2) -> false()
 function(p(),0(),dummy,dummy2) -> 0()
 function(p(),s(0()),dummy,dummy2) -> 0()
 function(p(),s(s(x)),dummy,dummy2) -> s(function(p(),s(x),x,x))
 function(plus(),dummy,x,y) -> function(if(),function(iszero(),x,x,x),x,y)
 function(if(),true(),x,y) -> y
 function(if(),false(),x,y) -> function(plus(),function(third(),x,y,y),function(p(),x,x,y),s(y))
 function(third(),x,y,z) -> z
