New issue 1059 by corh...@gmail.com: Assignment of a variable using  
extended variable syntax creates a new test variable with the same name
http://code.google.com/p/robotframework/issues/detail?id=1059

Attempting to assign a property of a Python object using the extended  
variable syntax counter-intuitively creates a new test variable with the  
same name as the extended variable.

Robot Framework 2.6.3 (Python 2.7.2 on win32)

Test suite:
*** Settings ***
Variables         vars.py

*** Test Cases ***
Test Extended Variables
    Should Be Equal    ${foo.bar}    hello
    ${foo.bar}=    Set Variable    goodbye
    Should Be Equal    ${foo.bar}    goodbye
    Should Be Equal    ${foo.bar}    ${foo.getbar()}

vars.py:

class Obj(object):
    def __init__(self):
        self.bar = "hello"
    def getbar(self):
        return self.bar

foo = Obj()

Test output:
=====================================================
Extended Variables
=====================================================
Test Extended Variables                      | FAIL |
goodbye != hello
