probably the cleanest example I have seen so far, & I still cant see the point the most enlightening thing here for me is your comet about it being a $1000 term for a $5 concept. I don't think I am missing anything by not bothering with them YMMV -- "The C Programming Language -- A language which combines the flexibility of assembly language with the power of assembly language." -- https://mail.python.org/mailman/listinfo/python-list
