Implement def, which simulates a python def statement, allowing you to write code like (def f(x y) ( x y)). The above expression should create a function with parameters x and y, and body ( x y), then bind it to the name f in the current frame. Note: the previous is equivalent to (def f (x y) ( x y)). Hint: We strongly suggest doing the WWPD questions on macros first as understanding the rules of macro evaluation is key in writing macros. (define-macro (def func args body) 'YOUR-CODE-HERE)
