In this case, your best bet might be simply "setopt magicequalsubst".
That means all "=" on the command line are treated (roughly) like
assignments for the purpose of expansion.  Unless you regularly have =
as part of a file name that should be fine.

Detailed configuration of completion tends to be quite murky as its
specific to the context you're in.  The usual answer would be to
write a completer for dmd using _arguments and tell it that
-of is an option accepting "=" and taking file arguments.  There
are umpteen examples of this in the completion system.  We'd
distribute a completion for _dmd if someone wrote one.
