RAII is a very common C++ idiom; that kind of thing'd be obvious to 
anyone who's mired^Wimmersed in C++ on a regular basis.

That's the point here - if this was the language technology already in 
use, then it'd be obvious, and nobody would think much about it. It's 
not, so it looks alien, much like any other alternatives that'll get 
raised along the line of C-plus-stuff look alien. Amongst C++ users with 
taste (and I claim that they do exist) the natural question that'll then 
be asked is, since you can already express this idea in C++ why would 
you adopt a less widespread (or novel) language?

There's no convincing English-language argument that this sentence is true.
