See https://underscore.io/blog/posts/2019/12/12/tut-to-mdoc.html for a motivation. Previously, the best workaround for redefining the same variable name was to use `reset`, which was not a great workaround because it clears all the existing statements in scope. Now, uses can use the `nest` modifier to introduce a new scope that allows redefining the same variable names while still accessing existing variables in scope.
* Fix bug when used in combination with reset * Report error when using `nest:reset` since it's redundant * Add more test cases stressing nest+reset combinations
