Note the sentence I quoted from Philip's email.

PIPESTATUS is a bash-specific feature, so it in no way "works
everywhere".  It won't even work on all GNU/Linux systems, including one
of the most popular (Ubuntu).  And it has almost no chance at all of
working on any non-GNU/Linux system.

It would make my "real life" job so much easier if people writing
scripts would understand that bash != sh, and that bash is not available
everywhere...
