100%, just try yourself.

Why would the symbol be defined in the executable? `dimedll.d` 
isn't compiled into the executable.

The code is using Phobos std.stdio.writeln templates, so the ~20 
KB for both exe and DLL are to be expected and IMO absolutely 
acceptable.

DMD's DLL support is waaay behind LDC's, especially once stuff 
gets more interesting than trivial examples.
