Both fstream and iostream are useful too. You said that there is no
filesystem in the browser, however I need to open files in C++ to load
data like scripts, textures, configs, etc.  Duetto have to workout this
somehow like via http requests or preloading files into the scripts.

About iostream, it is useful for printing information for debugging
purposes with std::cout, for instance I tried using printf from cstdio
just to see what would happen and it did nothing, I got no output in my
javascript debugger from firefox or chrome, I think that should me
implemented too.
