Summary of the new feature/enhancement

The type of $_ can be inferred for ForEach-Object/Where-Object but not in the ForEach and Where magic methods:

$script = '@(0..10).ForEach{ $_.'
TabExpansion2 -inputScript $script -cursorColumn $script.Length

Should return the same as

$script = '@(0..10) | ForEach-Object { $_.'
TabExpansion2 -inputScript $script -cursorColumn $script.Length

Proposed technical implementation details (optional)

The code above is the start of $_ type inference, a case just needs to be added for ForEach/Where similar to the others.
