// if a has a process
if( a.process ) …

// if processing a was successful
if( process(a) ) ...

// copy a to b
a.copy_to(b)

// copy b to a
copy_to(a,b)

// print a on stream f
f.print(a)

// print f and a on std out
print(f,a)

// count the number of people, cars and drinks
count(people,cars,drinks)

// count the number of cars and drinks people has
people.count(cars,drinks)

If you have namespace operator "::" in c++ or "'" in Ada (IIRC) 
and extension methods

// access library "as" extension method string
obj1.as'string

etc…
