-i is a useful feature:

Does dmd compile auto-included files separately? Does it generate temporary object files? If so, where does it write the files? Would -i cause race conditions on the file system?

Thank you,

I believe -i behaves as though you manually typed the names of the source files on the command line.  So it would do what the compiler would usually do in the latter case.

AFAIK, that means it loads everything into memory and produces only a single object file for the final executable. Separate compilation only happens if you invoke the compiler separately for each source file or group of source files.

Yes, this is correct.

If the `-c` flag is passed, the compiler will produce one object file for each source file. If the `-c` flag is **not** passed, it will produce one executable and one single object file.
