# This code has been run through a basic smoke-test.
package My::Error::String;
use overload
'""' => \&stringify,
'0+' => \&boolify,
fallback => 1;
sub new {
my $class = shift;
my $error = shift;
bless \$error, $class;
}
sub stringify {
my $self = shift;
return $$self;
}
sub boolify {
return;
}
Then, when you want to use it, you'd do something like:
use My::Error::String;
sub func_with_error {
if ($have_error) {
return My::Error::String->new( "Have an error somewhere ..." )
+;
}
}
Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
