docs: Search for `code` in source and return a list of `Match`\es
  
          `code` can contain wildcards.  ``${name}`` matches normal
          names and ``${?name} can match any expression.  You can use
          `Match.get_ast()` for getting the node that has matched a
          given pattern.
