All output from the block is written into the output pipeline, even if the output of the block should be redirected into a variable, or a pipeline inside the function:\r\n\r\n```\r\nfunction x([switch]$p) {\r\n    $null = foreach ($a in @(1)) {\r\n        echo \"this should not be visible\"\r\n        if ($p) {return}\r\n    }\r\n}\r\n```\r\n```\r\nfunction y([switch]$p) {\r\n    $null = try {echo \"this should not be visible\"; if ($p) {return}} catch {}\r\n}\r\n```\n\n### Expected behavior\n\n```console\nPS\u003e x\r\nPS\u003e y\r\nPS\u003e x -p\r\nPS\u003e y -p\n```\n\n\n### Actual behavior\n\n```console\nPS\u003e x\r\nPS\u003e y\r\nPS\u003e x -p\r\nthis should not be visible\r\nPS\u003e y -p\r\nthis should not be visible\n```\n\n\n### Error details\n\n_No response_\n\n### Environment data\n\n```powershell\nName                           Value\r\n----                           -----\r\nPSVersion                      7.3.0-preview.6\r\nPSEdition                      Core\r\nGitCommitId                    7.3.0-preview.6\r\nOS                             Microsoft Windows 10.0.19044\r\nPlatform                       Win32NT\r\nPSCompatibleVersions           {1.0, 2.0, 3.0, 4.0…}\r\nPSRemotingProtocolVersion      2.3\r\nSerializationVersion           1.1.0.1\r\nWSManStackVersion              3.0\n```\n\n\n### Visuals\n\n_No response_","author":{"url":"https://github.com/MatejKafka","@type":"Person","name":"MatejKafka"},"datePublished":"2022-08-03T19:24:30.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":18},"url":"https://github.com/17836/PowerShell/issues/17836"}
