Looks pretty well tested, nice!But in other less nice things, I take it you did not test with GDC? GDC does not support cli args with the same names as dmd. One of these is -mv.
The file structure of subPackage/alid/subPackage will not require it and you will not have the cross import issues, where if you depend on errornogc you can also import (and then get linker errors) for circularblocks.
