Open PoshAJ opened 3 months ago

PoshAJ commented 3 months ago

Steps to reproduce

Invoke-ScriptAnalyzer -ScriptDefinition 'foreach ($Host in $foo) {}'

Expected behavior

The Variable 'Host' cannot be assigned since it is a readonly automatic variable that is built into PowerShell, please use a different name.

Actual behavior
