Check out autodie::exception.

  try {
    use autodie;
    open my $fh, '<', '/dev/fail';
    ...
  } catch {
    if ($_ ~~ 'open') { ... }
  };

This behavior would fail without lhs overloading.  I'm not saying whether this
is a bad this, just now, but what's a programmer to do, here?  Overload eq?

So, I wanted to show that this is not only for junctions, and is already in
use, and to ask what you think of it.
