There are no unimplemented methods.  They just aren't being linked in.   
All is fixed with a main method.

If you wish to compile code without linking, you can do it via dmd -c.   
Then you will not get linker errors without a main method.

General rule of thumb -- if you are getting linker errors, most likely the  
issue is with your build (i.e. you aren't passing enough stuff on the  
command line, or in the right order).  The one exception is the main  
function, which is always expected by the linker, and must be provided by  
you (it's not in any library).
