[VOTE] Allowing use of exceptions in the engine

Hi internals! I opened the vote on the "Exceptions in the engine" RFC: https://wiki.php.net/rfc/engine_exceptions#vote The vote has three options, "Yes", "No" and "Yes, without E_RECOVERABLE_ERROR changes". The last option is a version of the proposal without BC issues. Some further notes: * I will not be including something like BaseException. Introducing it for this purpose seems like bad design and will be very hard to get rid of in the future. As the proposal (without recoverable errors) does not break BC [1] even without it, I don't see a reason to introduce it. * Some people suggest to use different subclasses of EngineException for different error types. I'm not against that, but I think it's okay to do that in a separate proposal, if someone can come up with a good selection of exception classes. It's much easier (and does not break BC) to add subclassing later, than to add suboptimal subclass types now and try to fix something like the SPL exception mess later. * The suggested uncaught exception error message change is just a bit of cosmetics (and not directly related to this proposal), so I'd like to do that separately. And regarding the vote: If you are in favor of the proposal in general, but want to have it in PHP 6 rather than PHP 5.6, then vote "No" here. If it fails now, someone can revive this once the time for PHP 6 has come. Thanks, Nikita [1]: We don't have a formal definition for this, but it seems to be general consensus that relaxing error conditions does not constitute a backwards compatibility break.
