I am not sure, if in ocaml we write
let f = Hop.a;
where f and Hop.a are methods, does the compiler "short-circuit" the call,
or not?
Does anyone know? How can we find out? A benchmark?
regards,

Yes, it does. Applications of function f will go straight to the code
for Hop.a. Contrast this with
let f x = Hop.a x
where an additional call (from f to Hop.a) would occur.
