Sneaky ;) I think there's probably a cleaner way to do this, but this
method is convenient.

That said, the best wrapping for a read/write interface is to use ports.
Guile's port implementation is terribly nasty, but it is possible to
implement custom port types. (gnome gnome-vfs) shows how to do it. Then
you have all the normal functions and port behavior.

g-wrap could provide some abstractions for port-like interfaces, but it
would need to be implemented, and guile needs some cleaning up, too.

Just a suggestion :)
