Steps to reproduce
Executing the following script in PowerShell 7.4.0 results in an unexpected behavior which also differs from PowerShell 5.1
function foo($x) {
$val = switch ($x){
1 { 5 }
default {
return 10
}
}
Write-Host "Val is $val"
$val + 1
}
Write-Host "foo 1: $(foo 1)"
Write-Host "foo 2: $(foo 2)"
PS 5.1 output:
Val is 5
foo 1: 6
foo 2: 10
PS 7.4.0 output:
Val is 5
foo 1: 6
foo 2:
It's not clear if this is a bug or simply a documente change from classic PowerShell, but it certainly behaves in a way I don't find intuitive.
Expected behavior
PS> <execute script>
Val is 5
foo 1: 6
foo 2: 10Actual behavior
PS> <execute script>
Val is 5
foo 1: 6
foo 2:Error details
