Powershell: Bug in Get-ChildItem -exclude ?

Question

Anyone have a workaround for the following behaviour in psh?

Get-ChildItem -path test -recurse -filter *.cs | foreach-object
-process { $_.FullName }

C:\scripts\test\AssemblyInfo.cs
C:\scripts\test\file1.cs
C:\scripts\test\file2.cs
C:\scripts\test\Foo.Designer.cs
C:\scripts\test\sub\file1.cs

Get-ChildItem -path test -recurse -filter *.cs -exclude "*Designer*",
"AssemblyInfo.cs" | foreach-object -process { $_.FullName }

C:\scripts\test\sub  <------------ This is a folder.  Why is it
included???  How can I exclude it?
C:\scripts\test\sub\file1.cs
C:\scripts\test\file1.cs
C:\scripts\test\file2.cs

Get-Help Get-ChildItem -detailed
...
    -exclude <string[]>
        Omits the specified items. The value of this parameter
qualifies the Path parameter. Enter a path element or pattern, such as
"*.txt". Wildcards are permitted.

        This parameter does not work properly in this cmdlet.  <-------
They weren't joking!

You can add | ? {$_.psIscontainer -eq "false"}
