24# This test is testing that single value variables are "stolen" when processing the inheritance
25# graph. i.e. if you have a graph like this:
26#
27#   B   A
28#   |\  |
29#   | C |
30#    \ \|
31#     \ D
32#      \|
33#       E
34#
35# The same variable is defined in both A and B. In D, the value from A is chosen because it comes
36# alphabetically before C. But then in E, the value from D is chosen instead of the value from B,
37# because the value of B was "stolen" and sucked into C, leaving B with no value set.
