BTW the alias to avoid a name conflic on "Generator" isn't 
necessary anymore with the last version of phobos (as shipped 
with DMDv2.073.0). However it's still conflicting with the latest 
version of LDC available on my system (1.0.0, based on 
DMDv2.070.2) so maybe letting it be in the example a bit longer 
is appropriate. Otherwise I believe you'll agree that removing it 
would make it easier for the beginners.
