Well, that is why I am hoping people who actually use the error handling
speak up.  The error handling was only added on September 12 with the 1.00
release.  I've not known of many people using it, and the fix for it is
very simple (I could provide 2-3 lines of code anyone could paste in to
port their existing scripts).  So I don't think it would be a big deal to
change it at this point, but it's basically now or never.

So anyone who uses the error handling (the new error handling as of 1.00),
speak up now.  :D

Just as a recap for those who haven't used it, it is enabled like this:

  my $glue = new Mac::Glue 'App';
  $glue->ERRORS(\&error_handler);

Or per-event:

  $glue->some_event($value1, param2 => $value2, ERRORS => \&error_handler);

So it just means changing, or adding a couple lines to, the error handler.

Thanks,
