Thank you for bringing that good example. Forbidding arbitrary 
extensions for D code, and enforcing a common standard name helps 
avoid mistakes like those ".c" extensions in the C++ sources, 
that numerous persons keep criticizing. The advantages of a 
standard suffix for D code are way larger than the disadvantages.
