because you'll open the file twice!

once in the FileHandle (which is never going to be used) and then again in the FileStream!

of course the way to go would be to fully rely on FileHandles,
but then somebody (hint hint) has to implement a full FileStream protocol
on top of the FileHandles ;)

In the future we will do this since it nicely separates the stream source
(based on bytes) from the actually streamed data (mostly characters).

but for now this is additional work :/

AFAIK I had all the tests running in my image, so what's the problem
again here? (I missed the whole discussion earlier :P)
