There was a problem hiding this comment.
Will search in all the ScriptBlockText [ any caracter ] that can be prone to FP , but with the selection_module_export_enum it should be fine, isn't it ?

Summary of the Pull Request
Adds a new Windows PowerShell ScriptBlock rule to detect scripts that enumerate
Microsoft.PowerShell.Utility exported commands and invoke cmdlets indirectly by
array index. This behavior can be used to avoid explicit references to cmdlets
such as Invoke-RestMethod or Invoke-Expression.
