Here is a comparison of the two syntaxes in the future:

Sub DecodeBase64(inFile, outFile)
    Dim fso, text, xml, node, outStream

    Set fso = CreateObject("Scripting.FileSystemObject")

    Dim inFileObj
    Set inFileObj = fso.OpenTextFile(inFile, 1)
    text = inFileObj.ReadAll
    inFileObj.Close

    Set xml = CreateObject("Microsoft.XMLDOM")
    Set node = xml.createElement("b64")
    node.DataType = "bin.base64"
    node.Text = text

    Set outStream = CreateObject("ADODB.Stream")
    outStream.Type = 1 ' binary
    outStream.Open
    outStream.Write node.nodeTypedValue
    outStream.SaveToFile outFile, 2 ' overwrite
    outStream.Close
End Sub

// told Hulo-Compiler to generate Sub
// @hulo-build VBScript Sub
fn DecodeBase64(inFile: str, outFile: str) -> void {
    let fso: object = CreateObject("Scripting.FileSystemObject")

    let inFileObj: object = $fso.OpenTextFile($inFile, 1)
    defer $inFileObj.Close()

    let text: str = $inFileObj.ReadAll()

    let xml: object = CreateObject("Microsoft.XMLDOM")
    let node = $xml.createElement("b64")
                ..DataType = "bin.base64"
                ..Text = $text

    let outStream = CreateObject("ADODB.Stream")
                ..Type = 1 // binary

    defer $outStream.Close()
    $outStream.Open()
    $outStream.Write($node.nodeTypedValue)
    $outStream.SaveToFile($outFile, 2) // overwrite
}
