On the Nim forum, locate the search bar. Use it to find discussions related to 'macros' or 'metaprogramming'. If a direct search is not possible, identify a relevant post by browsing. Provide the title of one forum post related to these topics.
Navigate to the Nim forum at 'https://forum.nim-lang.org/' Locate the search input field (id: 9). Fill the search input field with 'macros'. Since direct key presses (like Enter) cannot be simulated, and no explicit search button is present, assume the search functionality might be triggered by navigating to a different page or by an implicit action not directly observable. Browse the visible forum topics for any relevant to 'macros' or 'metaprogramming'. Identify and state the title of one relevant forum topic.
Successfully navigate to the Nim forum. Successfully identify and fill the search input with 'macros'. State the title of at least one forum topic that is clearly related to 'macros' or 'metaprogramming' (e.g., 'Macros in Nim', 'Advanced Metaprogramming with Nim').
