AFAIK `-o-` became the "undocumented" way to turn DMD's entire backend off.

> I think `dmd -o- main.d` should generate the `main` executable, but not the `main.o` object file.

Hmm, how would you turn off object generation then?
Note that dmd -ofmain main.d won't generate an object file, but only the main
executable.
