That's correct, I believe, but I also think the underlying problem here is having support for dynamic filehandles which can be exported. You could assign something to $fh and then call open(), but that won't give you what the code asks for.

It should in principle be possible to replace
 my $fh = undef;
 open ($fh..)
with
 use FileHandle;
 my $fh = new FileHandle (...)
etc.
which works also on Perl 5.6.

When I first ran into this I did a little bit of hacking in that direction, but I didn't make a full effort and didn't get it to work - in the meantime the customer system which required perl 5.6 (for performance reasons) migrated to a later version of AIX and I was then free to upgrade the perl version to 5.8 on this (my maintance copy of their system), in other words I wasn't affected by the problem anymore and abandoned what I had started working on.
