As argued below, no enumeration should take place at all.\r\n\r\n\r\n### Expected behavior\r\n\r\n```console\r\nOhElement\r\n```\r\n\r\ni.e., the name of the element, as if you had applied `.ToString()` to the instance.\r\n\r\nNote that even though such instances technically implement `IEnumerable`, for consistency with pipeline enumeration behavior I expect them _not_ to be enumerated.\r\n\r\nI suspect that the bug is related to the fact that they _are_ enumerated.\r\n\r\n\r\n### Actual behavior\r\n\r\n```console\r\n(An empty line prints.)\r\n```\r\n\r\n\r\n### Error details\r\n\r\n_No response_\r\n\r\n### Environment data\r\n\r\n```powershell\r\nPowerShell 7.5.0-preview.5 (problem dates back to Windows PowerShell)\r\n```\r\n\r\n\r\n### Visuals\r\n\r\n_No response_","author":{"url":"https://github.com/mklement0","@type":"Person","name":"mklement0"},"datePublished":"2024-10-30T20:07:52.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/24508/PowerShell/issues/24508"}
