Ehm. There's any number of arguments that can be made to question the 
validity of the study:

* the coding style does not use the entire language in either or both 
implementations

* the application domain favors one language or the other

* the application's use of libraries is too low/too high

* the translation is too literal

* the translation changes the size of the code (which is the case here, 
as the D version is actually shorter)

Nevertheless, I think there is value in the study. We're looking at a 
real nontrivial application that wasn't written for a study, but for 
actual use, and that implements the same design and same functionality 
in both languages.
