Some API suggestions

[schmittjoh]

I've some suggestions for the API after trying this a bit. Basically, I'm wondering what you think about something like this:

Attempt::call($someCallable)
    ->forAll($onSuccess)
    ->always($always) // Finally semantics (called regardless of success/failure)
    ->throwIfFailed()
;

This would be equivalent to:

try {
    $rs = $someCallable();
    $onSuccess($rs);
} finally {
    $always();
}

Not sure if this is already supported in another way, but I haven't found anything. What do you think?
