If the V1 program has

char[] x = any.std.string.StringFunctionFromV1();

it won't compile because it complains about the type conversion.

Also, because a version block has to be syntactically correct, you can't isolate v1/v2 differences because the syntax has changed.

Both problems have solutions, look here:
