Not sure if I understand you correctly, but you're allowed to 
omit the module declaration, if that helps:

https://dlang.org/spec/module.html#module_declaration

"The ModuleDeclaration sets the name of the module and what 
package it belongs to. If absent, the module name is taken to be 
the same name (stripped of path and extension) of the source file 
name."
