I completely agree.  The key to RAII is not that Resource Acquistion Is
Initialization but its converse -- End-of-Life Is *Automatic* Resource
Release.

You can fake the former easily in C ("no lazy initialisation") - the
converse is much much harder.  To release resources in C but you *have*
to do it all by hand (or use a GC, if the only resource you're
interested in is memory), which is absolutely not "works just as well in
C" unless you have unlimited programmers, unlimited patience or
unlimited time.
