Using `<` and `>` for generics is not only bad due to their primary meaning as comparison operators, but also due to having to special handle `>>` in the lexer.

Using `<` and `>` for generics is not only bad due to their primary meaning as comparison operators, but also due to having to special handle `>>` in the lexer. It took almost 30 years before the C++ standard supported expressions like `std::vector<std::vector<int>>`. For some reason, Bjarne Stroustrup managed to pick the only two character in C that could be merged into a different lexeme.
