Passing an integer by reference in Python
...there is basically a complete bijection between Java/Python references and C++ pointers to objects in semantics, and nothing else describes this semantics as well. "They don't have to be dereferenced" Well, the . operator simply dereferences the left side. Operators can be different in different lan...

The data represents the static part of the stream; the read and write methods the dynamic part of the stream...
What is the difference between include and require in Ruby?
... like in class or even a method definition. This means you can do mixin in C++ by writting some methods in a file and include it in the code of a class, exactly has you would do in ruby. So they are not that far, even though it's indeed not a common practice in C's.
