Re^3: How many different ways can Perl code fail?

Why is using $@ a bit unreliable?

Update: Just found that the answer to this is covered by the documentation of Devel::EvalError. A quick read seems to suggest that the issue can only arise if there's a DESTROY method which uses eval (however indirectly) and doesn't localise $@.

You'll have to decide whether that would be a problem for you...

Not really. It's not like it's harder to handle the problem. I'd say it's even cleaner.

eval { ... };
if ($@) {
   ...
}

vs

eval { ...; 1 }
   or ...;

and

my $x = eval { ... };
if ($@) {
   ...
}

vs

my ($x) = eval { ... }
   or ...;
