Oh, I didn't mean it that way.  I was continuing from your findings
that certain features of "local" may not have been available in
0.5.10; hence the hits from grep that showed any assignment might be
problematic with that version and we may need to downgrade our
scripts.

But as Szeder writes in a response later in the thread, assignment
on "local" may have been avaiable in versions before 0.5.11 in a
limited form (namely, it is split at $IFS unlike normal assignments,
which was the starting point of this thread), which reduces the
scope of downgrading necessary by a large margin ;-)
