Because I spent months of my life a few years ago trying to work on modernizing the Python interpreter and it made me a bitter person. There is so much bizarre behavior in the interpreter that people depend on which is entirely undocumented and non standardized. Very few people know what even such a simple thing as "a + b" does in the language.
