stderr/stdout/stdin are __gshared and can't be referenced by
safe code. The module level version of writeln, etc., access a
trusted version of stdout to avoid this.
Yeah, the standard library still has a ways to go even with @safe.
I always imagined that the standard pipes should use shared as
opposed to __gshared. I don't think the current implementation is
thread-safe, but I don't know how this affects in memory safety
in this case.
