Interestingly, the look of C++ apps have changed *substantially* over 
time as new philosophies of how to use it have evolved.

One could note that I'm a bit stuck in the past, as my C++ code (the D 
front end) is definitely an old style of C++. It has very little in 
common with the modern style (see Boost for that).
