Basically I (myself Vijay) am a C/C++ developer
as i want to implement generic data type in C. i was searching in the google.
then i come across similar kind of implementation in the python develoer chain.
i was going through some of the mailing chain in [python-dev] section(below is the link)
This has to do with the fact that the Python Interpreter is written in C, not with the Python language intrinsically. So you might better post this in the C/C++ Forum.
