We were talking about smart pointers - basically, instead of doing
something like:
obj *foo = new obj();
...
<many lines of code and exit points>
...
delete foo;
You might do:
pg_smartptr<obj> foo;
...
<many lines of code and exit points>
...
Note the lack of a delete - that's the point here; it's not needed
because as soon as the smart pointer goes out of scope, it's
destructor will delete foo. That means you don't have to remember to
include the delete in each of the many exit points of the code.
