This is almost certainly not coincidental.  In the early years of zsh
development, ksh was only available on closed-source UNIX platforms,
so any ksh-isms that were incorporated were either derived from reading
man pages (which led by misunderstanding to the "coproc" command and
an unusual syntax for writing base-N values in arithmetic context) or
borrowed from pdksh.

I don't see any reason not to accept this patch.
