Idea seems good. There is no cross-platform fopen flag to open the file only if it *doesn't* exist. glibc has the 'x' mode as a private extension, but that does...

A `File` constructor (or `open` / `reopen` overload) which exposes all common POSIX an Windows flags and creates a `FILE*`/`File` using `fdopen` / `windowsHandleOpen` would be nice - it could...
