Contributions summary:Andreas's contributions centered around extending the CoffeeScript language to support ES6 generator functions. This involved modifying the lexer, parser, and code generation logic to handle the `yield` keyword, `yield from`, and allow functions to be automatically treated as generators when using `yield`. They implemented new tests to verify the correct behavior of generators in various scenarios, including within for loops, switch statements and nested contexts. Furthermore, the user removed the `yield` keyword from the reserved words and improved existing test cases.
