I agree. What I would also like to see is a good method of manipulating
the environment variables of the current process. Sure, there's getenv(),
but it's not exactly a great interface, and there is no portable way of
setting one.
But basically, when I pass environment variables to a child, I might want
to make them a modified version of the current environment, and for that
I'd expect the library to provide a way to access current variables.

Win32's HANDLE is a pointer type. Does that count as integral?

Excellent work on the library, all in all.
