Description

Found an encoded list token string in a scalar string context. Use 'Fn.element(list, 0)' (not 'list[0]') to extract elements from token lists does not seem to help people. Maybe we should link to a documentation article to clarify

I'd propose to close this as a duplicate of #2254 – what do you think, @DanielMSchmidt?

I don't think they cover quite the same topic although it's about the same error message. This issue proposes rephrasing the error message as well as linking to a documentation page that helps, the one you linked talks about hinting towards iterators. We can combine them, but I don't think they are the same
