Why not something like the following:
shared_ptr<FILE> foo(fopen("foo.txt","r"),
call_if_arg_not_null(fclose));
With call_if_arg_not_null being a functor (based on boost::function or
whatever) that simply calls fclose only if the argument is nonzero.
I think the obvious rationale is that while both approaches have their
merits, you can indeed implement the one based on the other but not vice
versa.
