Refactor the code to move inside 'let' or 'begin'. Also, in the test position of a 'if', recognize the 'not' inside a 'let' or 'begin'. For example, transform (if (begin ... (not p)) x y) => (if (begin ... p) y x) Previously, this conversion was made only when the 'not' was the outermost expression. And use the refactored code to move application inside 'let' or 'begin' in a single step For example, transform ((let (...) ... (let (...) ... f) x) => (let (...) ... (let (...) ... (f x)) In the conversion, it's necessary to shift x to the new coordinates inside the 'let's. In the new version x is shifted only once. |
