"Resource Acquisition is Initialization". The primary benefit from RAII is
ordering resource initializations so that you don't end up with an
innumerable number of failure combinations, and limiting shared ownership of
resources, preferable in a strongly hierarchical arrangement. It's not in
automatic destruction of automatic storage objects, which is comparatively
more useful in C++ than C because in C++ the exit from a routine could be
involutary given exceptions.

Proper ordering of resource mangement in C also gets you the majority of
these benefits, a result not of language features but of good programming
habits. Comparing poor resource management in C with good resource
management in C++ is comparing apples to oranges. If programmers were so
inept at tracking memory anyhow, they'd be best in a GCd environment. If
they feel the impulse to allocate dynamic strings randomly where ever it
suits them, then they're begging for leaks, and really should be using a GCd
language, whether in C or C++. If they properly order allocation of these
resources, then the gap between C and C++ becomes quite small; maybe not
small enough, but perhaps for other considerations to move to the forefront.

[I'll refrain from commenting on the obscene nested containers example as
I'm sure it made you cringe as well.]
