in scientific computing or simulation,
typically for advocacy like it takes 10 lines in OCaml to do this,
you would use 50 lines in C++ to do the same thing;
Maybe OCaml for Scientist from Jon Harrop can be a good start. There

Hi,
Well, we talk about this a little bit, but here is my opinion:
- calling a C function to add a single int
a 64bits bigarray on a
32bits arch result in a C call, but otherwise it's handled by the
compiler.
Indeed I just test and you are right. I must have experienced this
