Powershell: Multiple returns

I stumbled upon a unexpected behavior in Powershell the other day. A colleague of mine hade a code snippet similar to the following lines:

function create-directory($name)
    md $name
    return (test-path $name)

$result = create-directory "c:\temp\temp2"

I expected $result to contain true but… no! Instead it was an array with two elements; one of type DirectoryInfo and one boolean. It turns out that Powershell allows multiple returns. This means that we can write functions like:

function multiple-returns

Such a function will return an array of three string elements; John, Robert and Richard(!).
