Traverse an AST (a list of expressions) and change calls of the form
<code>. = ottr::check(...)</code> so that they are appended to a list with name <code>list_name</code>.
If <code>list_name</code> is <code>check_results_XX</code>, then <code>. = ottr::check(...)</code> becomes
<code>check_results_XX[[&lt;int&gt;]] = ottr::check(...)</code>, where <code>&lt;int&gt;</code> is an integer

An R autograding extension for Otter-Grader (<https://otter-grader.readthedocs.io>). It supports
