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 such as the following:

int main(){

RWCollectableString* string = new RWCollectableString;

RWFile file("mydata.dat");

// WRONG:

file >> string; // Memory leak!

// RIGHT:

delete string;

file >> string;

return 0;

}
