This seems dangerous as it ties to the lifetime of another object. In some cases this vector is not even necessary to be owned by the user since it is not used outside of the `TokenList`. It looks the list this could just be owned by `TokenList`\n\nThis supported by the fact that the copy constructors and assignment operators copy the reference which means that two different instances will modify that \"global\" vector which is obviously wrong and will cause issues.\n\nThere was some usage which provides the input file via that vector parameter instead of (or additionally) to the filename parameter. This allows to tokenize multiples explicitly but I am not sure if that is even necessary. This might have contributed to the assumption that it is necessary to provide that vector.","author":{"url":"https://github.com/firewave","@type":"Person","name":"firewave"},"datePublished":"2025-04-07T07:02:50.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/424/simplecpp/issues/424"}
