BROKEN: treats [int] as an *index* expression\r\n```\r\n\r\n\r\n\r\n### Expected behavior\r\n\r\n```console\r\nOverloadDefinitions\r\n-------------------\r\nstatic T[] Empty[T]()\r\n\r\nstatic int[] Empty[int]()\r\n```\r\n\r\n\r\n### Actual behavior\r\n\r\n```console\r\nParserError: ...\r\nLine |\r\n  51 |  [Array]::Empty[int]\r\n     |                 ~\r\n     | Array index expression is missing or not valid.\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 Core 7.3.0-preview.5\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":"2022-07-12T13:21:57.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":7},"url":"https://github.com/17668/PowerShell/issues/17668"}
