PowerShell equivalent of LINQ Any()?

Question

I would like to find all directories at the top level from the location of the script that are stored in subversion.

In C# it would be something like this

Answer 1

A variation on @JaredPar's answer, to incorporate the test in the Test-Any filter:

function Test-Any {
    [CmdletBinding()]
    param($EvaluateCondition,
        [Parameter(ValueFromPipeline = $true)] $ObjectToTest)
    begin {
        $any = $false
    }
    process {
        if (-not $any -and (& $EvaluateCondition $ObjectToTest)) {
            $any = $true
        }
    }
    end {
        $any
    }
}

Now I can write "any" tests like

> 1..4 | Test-Any { $_ -gt 3 }
True

> 1..4 | Test-Any { $_ -gt 5 }
False
