Yes, I understand what exists does, however perl -w still hates this code:
my %h;
$h{stuff} = undef;
die if (exists $h{"stuff"} && $h{"stuff"} ne "");
To be precise, perl -w says:
Use of uninitialized value in string ne at test.pl line 5.
Just because something exists does not mean it is defined, which was my
point in the previous post.
Anyway, the patchset should be on its way to you shortly.
