type field ambiguity (possbile bug)

[sancho3]

If a child type method local variable shares the same name as a parent member field it blocks access to the parent field.
I think this could be a bug. I searched the bug reports and can't find anything.
Here is an example:

Code: Select all

Type parent  
	As Integer x1, y1, x2, y2 
End Type
Type child Extends parent 
	Declare Sub foo() 
End Type
	Sub child.foo() 
		with This 
			Dim As Integer x1, y1, x2, y2
			Dim as integer zx1  
			'x1 = .x1 		' error: element not defined 
			'x1 = this.x1	' error: element not defined 
			zx1 = .x1		' this will error as well unless you comment out the first dim as line 
		end With 
	End Sub

Related to the bug already reported a long time ago (2013-01-05):
#645 Access to global duplicated symbol is captured by local symbol
(#581 Locals break/override THIS access to inherited members)

A workaround exists in this precise case:
x1 = Base.x1

Yes that is the bug. I saw bug #645 in my search but I didn't think it was related.
Now that I read the comments I see that it is the same.
It is a bug that is not likely to be fixed, but as you point out its not a difficult workaround.
