Visual D has a "token replacer" that allows to do this: 
http://www.dsource.org/projects/visuald/wiki/Tour/TokenReplace

replacing "unittest { $anything }" with "unittest { }" (to not get into 
troubles with version conditionals before the unittest statement) 
reduces the size of datetime.d to about a third of its original size.
