Did anyone ever reply to this post?
I couldn't find it in the archives and I thinnk it's a pretty good question.
For instance would it be 'safe' and 'proper', and 'ok', etc... to do somethign like:
sub whatever {
my $foo = shift;
undef $!;
if($foo eq 'bar') { return 1; }
else { $! = "Foo must equal bar";return 0; }
}
TIA
Dan
