want the byte I just read, and need to push it back onto the stream. This
brings up (I think) two ways around the problem:
1) I'd like to be able to peek ahead at a byte, before actually consuming it. ie)
Yes, Parrot will get an "unget" and "peek". Now that the buffering layer is mostly working it should be quite easy.
I assume this would only be allowed to work if a buffering layer is topmost, right? That is, I shouldn't be able to do either to an io_unix layer.
I've had a bad bout with the flu for the last 7 days. As soon as I can sit
up again I'll see about patching it in.
Hope you feel better!
