It wouldn't make sense. It's nowhere near as bad as C++, but dmd has to 
recompile modules all the time unless you compile the entire program at once. 
When you run a build, every single module on the command line and all of the 
imported modules get compiled. Object code is generated only for those on the 
command line, but the others are still compiled. Any imported module which 
uses a .di file won't have as much to compile, and any templated code that 
doesn't get used in those modules won't get compiled, but there's still lots 
of recompilation going on if you compile your program incrementally. And D 
just isn't set up to compile only a portion of a module.
