Recently I wanted to wrap a small d program around an external process and stream its stdout/stderr to the original stdout/stderr of the d program (no other output while the external process is running).

I first tried to implement this with vibe's fibers, but after failing first try, I resolved to std.concurrency to get the thing done.

It's not a bad solution, but a fiber based thing should be so much nicer, so I tried again in an isolated project (https://github.com/gizmomogwai/vibe-process).

Unfortunately my v0 looks nice, but does not process the output as it should.
v2 is my favorite, but far aways from the clean solution of v0.

So the question is, how to make a nicer solution, that also really cleans up in the end.

Kind regards,
Christian
