[ANN] Metabash 0.0.0

Hello Guilers,

I started a project called Metabash -- it's a library for GNU Guile that
allows to create distributed pipelines that connect processes (akin to
Unix pipes) across different hosts:
  https://github.com/artyom-poptsov/metabash

I thought if would be cool to have such a facility for Guile.

Although this is an alpha release that contains a proof-of-the-concept
Metabash implementation, the basic functionality is already there -- see
the example in the README file.

Happy hacking!

- Artyom

This is really cool!

Maybe it doesn't make sense, but could the `(guile ...) be handled by the
same running process instead of creating another process, so you just pass
this to the plumber?

(let loop ((line (read-line)))
                                (if (eof-object? line)
                                  (exit)
                                  (begin
                                    (write-line (string-join (string-split
line #\:) ","))
                                    (loop (read-line)))))

Thanks!

Yes, it makes sense when a Guile code runs locally; it could be possible
to run the code in a different thread instead of spawning a new Guile
process.

On the other hand, I'd love to have uniformity in the way the Guile code
is handled in the pipeline, either locally or remotely; that also means
when executed locally it does not affected by the current program state
and cannot modify in any way as it would be if I'd run it in a new
thread.

Nevertheless, big thanks for thought-provoking suggestions and the
patch (I merged it today.)
