I think I'd need a toWStringz function, or maybe toStringz can be made more clever and figure out that I'm passing a wstring and return a null-terminated wchar*.
Currently I'm using wstrings and appending the null terminator by hand, e.g.: wstring appName = "DMapp" ~ "\0"; Some WinAPI functions in unicode form, such as CreateWindowExW, expect a wchar*. So in the above case I just pass `appName.ptr`. But it would be convenient not having to append the null terminator prematurely.
