Hi everyone,

I'm cancelling the vote on PREG_THROW_ON_ERROR.

The flag as it stands violates the throwable policy, as Tim's point shows.
That's not something to fix with the vote open, so I'm pulling it back
rather than changing the proposal out from under people who already
voted.

I'll keep the discussion here, and once things settle I'll start a fresh vote.
The RFC is back under discussion.

Thanks to Tim for catching this before it went further.

Regards,
Osama
