You can include a file as text using import("filename"), and you can  
convert it to code using mixin(string)
mixin(import("lib.d")); will work for you example.

*BUT*... You are completely breaking the module system and working against  
the language rather than with it.

I recommend you use the tool rdmd: "rdmd main" will pick up dependencies  
and add them to dmds command line.
