Return Type of operator>>()

An extremely common mistake is to forget that the functions:

Rwvistream& operator>>(RWvistream&, RWCollectable*&);

RWFile& operator>>(RWFile&, RWCollectable*&);

return their results off the heap. This can result in a memory leak like the following:

main(){

RWCollectableString* string = new RWCollectableString;

RWFile file("mydata.dat");

// WRONG:

file >> string; // Memory leak!

// RIGHT:

delete string;

file >> string;

}
