No, please don't! At least, not if you aren't equipped to handle the fallout yourself and not until these tools are further refined!

I'm a fish-shell developer and I just dealt with a user that was getting bizarre test failures. Turns out the developers didn't account for basic things like the normalcy of `cat` having its output fd closed mid-stream (e.g. you are piping cat to something and that something exits before cat does) and their vesrion bails with an exception dumped to stderr instead of silently closing with a non-zero exit code.
