Issue Description

For some reason it always complains that my variable is assigned but never used when I assign into a particular loop. Repro code:

$RequredFiles = @("c:\somefile1.txt","c:\somefiles2.txt")
$IsMissingFiles = $false

$RequredFiles | ForEach-Object {
if (!(Test-Path $)){
$IsMissingFiles = $true
Write-Host "Required file missing: $"
}
}

if ($IsMissingFiles){
Write-Host "Missing files"
}

Shows error:
file: 'file:///c%3A//test.ps1'
severity: 'Warning'
message: 'The variable 'IsMissingFiles' is assigned but never used. (PSUseDeclaredVarsMoreThanAssignments)'
at: '6,9'
source: 'PSScriptAnalyzer'
code: 'PSScriptAnalyzerdb99606b-bfb5-43be-8902-10233d7a4a8c'
I am experiencing a problem with...
False error message
