Fair enough, ... ..though sharing a global var between different
packages in the same file -- you admit that in public?? ;-)
and just my luck to use "a" and "b"... (me)-(foot)<-[bang]
BUT... this is a problem:
{ package A;
use vars qw($aa $bb $cc);
$aa=1;
$bb=2;
$cc=3;
our ($dd, $ee, $ff);
$dd=11;
$ee=22;
$ff=33;
}
{ package B;
use vars qw($aa $bb);
$aa=4;
$bb=5;
our ($dd, $ee);
$dd=44;
}
{ package A;
print "aa=$aa\n";
print "bb=$bb\n";
print "cc=$cc\n";
print "dd=$dd\n";
}
'
----
'dd' doesn't carry over to future mentions of package A...
and while 'aa/bb' do,
I have this in from 5.10:
NAME
vars - Perl pragma to predeclare global variable names (obsolete)
SYNOPSIS
use vars qw($frob @mung %seen);
-------------------
OBSOLETE?!?
What replaces this functionality? as shown above, 'our' doesn't
work.
