It's a classic RAII situation.
In C++, you'd do it...

...explicitly delete it or use 'auto' (meaning RAII this time).

  void somefunc()

    auto...

Couldn't we use malloc/free + RAII for that? ...auto_ptr<>?

...y = 20;
auto var f = new Foo(); // this will be RAII and automatically

...newsgroups, it seems like 'auto' as local raii and 'auto' as
