Let's say you want to write to a file:
std::ofstream of("out", std::ios::binary | std::ios::trunc);
The second parameter of the stream constructor is a combination of flags, and since this is by default not typesafe, it is a regular integer parameter. VAX is not aware of this, so it does not give any sensible suggestions here. If you already started typing up until "std::ios::", you get all kinds of useless suggestions from the ios namespace which do not make sense here.
Suggesting the allowed/sensible set of flags from std::ios for these standard library functions would be great. The same is true for the std::ios::beg/cur/end parameter for seek functions (and probably a few others I cannot remember right now).
I'm using the latest VAX on VS2015.
