This is the first time I have heard &quot;RAII requires exception&quot;.<p>But then reading the comments section, I get that the author completely missed the point.<p>The claimers, whoever they are, aren&#x27;t claiming RAII needs exception for deallocation, which the author has covered.<p>But they claim RAII needs exception to handle resource allocation failures. Which the author is trying to undermine saying that is a rare case. Which probably isn&#x27;t that rare.
