You should show more respect for them and their work. Their ideas 
seem very far from being crazy. They have also proved their type 
system to be sound. This kind of work is lightyears ahead of the 
usual sloppy designs you see in D features, where design holes 
are found only years later, when sometimes it's too much late to 
fix them :-)

That if syntax (that is integrated in a type system that manages 
the masks, plus implicit polymorphism that allows the same 
function to be used both in a vectorized or scalar context) works 
with larger amounts of code too, while you are just doing a 
differential assignment.
