I noticed that an `align(N) class ...` seems to be totally ignored; i.e., it has no effect on `Type::alignment()` and neither on `ClassDeclaration::alignsize()`. I checked the paddings too (and the tests cover them as well); they seem fine already, both inbetween header and payload (and for both D and C++ classes, the latter missing the monitor field) as well as inbetween base payload and derived payload.
