Issue Description

Powershell methods foreach and where are not highlighted after curly bracket. With parenthesis it works fine.

Example code:

@($group).where{$_.count -gt 1 -and $_.name}.foreach{...}

"where" is highlighted.
"foreach" is not highlighted and has a very general scope

Screenshots

Expected Behavior

The foreach should have a more specific scope.

Code Samples

@($group).where{$_.count -gt 1 -and $_.name}.foreach{...}
