What is the reason for the large time penalty

[Inververs]

Here are two examples:

1 - Object Property

2 - Object Method

$oIE = _IECreate('http://msdn.microsoft.com/en-US/')
$oAs = _IETagNameGetCollection($oIE,'a')
ConsoleWrite('> Object Property href' & @LF)
$iTimer = TimerInit()
For $oA In $oAs
$sHref = $oA.href
Next
ConsoleWrite(TimerDiff($iTimer) & @LF)
ConsoleWrite('> Object Method  href()' & @LF)
$iTimer = TimerInit()
For $oA In $oAs
$sHref = $oA.href()
Next
ConsoleWrite(TimerDiff($iTimer) & @LF)

@AutoItVersion = 3.3.9.4

The first example is much faster than the second.

1 - 50 ms

2 - 6400 ms

Why is this happening?
