Object properties assignment bug and WITH bug

[PELock]

I'm testing right now everything I can find (from the official help file)

Local $oExcel = ObjCreate("Excel.Application")
$oExcel.visible = 1
$oExcel.workbooks.add

With $oExcel.activesheet
    .cells(2, 2).value = 1
    .range("A1:B2").clear
EndWith

$oExcel.quit

It throws error:

"e8.au3" (2:8) : ==> Expected function call or assignment.:
$oExcel.visible = 1
$oExcel^ ERROR

And another associated bug, I've commented out the assignments:

Local $oExcel = ObjCreate("Excel.Application")
;$oExcel.visible = 1
;$oExcel.workbooks.add

With $oExcel.activesheet
    .cells(2, 2).value = 1
    .range("A1:B2").clear
EndWith

$oExcel.quit

And now it throws:

"e8.au3" (5:1) : ==> Keyword 'With' not valid at the start of a line.:
With $oExcel.activesheet
^ ERROR

Two issues, firstly With ... EndWith is not implemented. Secondly, the access operator is only accepted in its binary form, unary form needs to be added as well.

Third issue, objects are a special case in that expressions can form the left hand side of assignments. This third issue is the difficult one to solve, as it would require a change of the way assignment lines are parsed to use the full expression parser.

I understand it's a hard problem, but I don't expect any bugfix, since this is very complicated matter, I just want You to know what's wrong, and maybe in the future you might come up with an idea how to fix this.

[MattDiesel]

It's not that complex to solve, it just requires changes across the whole parser, so is likely to introduce other bugs.
