3.1
sometimes i have an argument that is a method call and could 
as well be computed by passing the args to the callee

example will make it clear:
private void foo(Set s){
   bar(s, s.size());
}

private void bar(Set c, int size){
   ....
}

the second parameter of bar is useless. It could be just computed:

private void foo(Set s){
   bar(s);
}

private void bar(Set c, int size){
   int size= c.size();
   ....
}

That of course only works sometimes. But maybe there's a simple and broad enough
pattern of useful cases.
