Cool. That feature will expose such incorrect changes that erased
Location information by someone e.g. incorrect Const replacement.
Everyone can know what is the cause of the location bug.

Until we support English - that means someday this test became
nothing and then you can't depend on this kind of tests.

Similar situations happened on early days of System.Data tests.
When Microsoft released .NET FX 1.1, both the type of expected
exceptions and error messages got changed and they highly messed
System.Data unit tests. I believe this will become messy version
by version.
