[5.5] Rescue helper

[BrandonShar]

Optionals introduced a great helper for one of my favorite pieces of terse ruby syntax, so I thought I'd take a stab at another.

This rescue helper would allow a terser syntax for a typical try catch pattern that returns a default of some kind. It's held back a bit by PHP's anonymous function syntax, but I still think it's fairly nice.

return rescue(function () use ($someClass) {
   return $someClass->method();
}, $someClass->backupMethod());

Thanks for the feedback, but that's a ruby specific hang up that doesn't apply here. PHP's catch(\Exception $e) doesn't include things like syntax errors, it's a much less broad.

Since we've got PHP 7 as minimum requirement maybe we should catch \Throwable interface then?

[BrandonShar]

I think that makes sense. I'm reading over examples of where that comes up now and it would be nice for things like TypeError

changed to Throwable. Good call @a-komarev
