For the people who can't live without them, Nim provides [https://nim-lang.org/docs/filters.html](https://nim-lang.org/docs/filters.html) ; an `#? expandTabs(tabwidth:int)` filter can easily be written. Personally, I think it's a bad idea and would recommend against including such a filter in the standard library.
