That's good to know; ysh[1] will treat pipelines with a SIGPIPE indicative exit code as successful to allow e.g.

  foo |head -n2

to be treated as successful. I haven't seen anyone complaining yet about rust programs breaking this idiom, but I'll keep an eye out for it.

In other shells, the status of the pipeline is the exit status of the last process, so in this case that would be head which exits with 0.

Not in e.g. bash with "pipefail" set. However the pipefail option in bash will choke on my previous example, hence treating a SIGPIPE the same as success in ysh.

Yes well, the pipefail option configures bash to do the opposite of its usual behaviour.
