Should fails when trying to compare std.container.array Ranges.

Morning,
It looks like Arrays (std.container.array) data types will cause test to not compile because the destructor is marked with @System. The error message looks similar to this:

@safe function ...should cannot call @system destructor std.container.array.Range(Array!string).RangeT.~this

Not sure what the correct solution is since there was an effort to make the code safe, but this is a valid range construct, so technically it should be supported. I personally have found the ability to compare ranges very useful since it provides diffs and therefore I personally would prefer it support all ranges.

It looks like it is a bug... All ranges should be supported. I will look over and see how this can be fixed. Maybe this can be easily fixed by making the assert function @trusted.

If I may suggest, perhaps it would be good to create tests to ensure that the asserts work for all of the built-in containers (std.container.*)? Or, at least a sufficient set. I know std.container.dlist works, but there's nothing that states that any of the other ones aren't going to cause issues.
