If a function is "insanely long" then inlining will have negligible 
effect. Funcall overhead is only relevant if the function is really 
short, so it spends nearly as much time calling the function as doing 
the actual work of the function, AND you call the function frequently 
enough that this overhead adds up to something significant.
