Note about some duplication of code between BslOCaml and BslJs:
The previous of libbsl was implemented using a functor for sharing some part of this process.
The experience has shown that the treatment done on Javascript and Ocaml is quite different,
which led to complex code in the argument of the functor, not very natural.
I (mathieu) think that proceding now with 2 different files is more relax, the implementation
can be different, without hacking the interfaces of functors and args.
