I am not sure wheter compiler arguments works at the shebang 
line. If it works there might be the issue, that the file is 
passed first to rdmd and then the compiler argument. Arguments 
after the file name are handled as application arguments and 
passed to the application.

What definitely works is using dub and single package file

You can define the versions in the json/sdl section.

Kind regards
