To me that is akin to building a car with no brakes and justifying it by 
saying it is "designed for experts." Sure, an expert who never makes any 
mistakes could effectively drive such a car. The trouble is, the road is 
full of non-expert drivers the expert ones are forced to interact with, 
and even the experts still make mistakes now and then.

I don't believe that having brakes impairs the performance of my car one 
bit.

I also would not say that C++ was deliberately designed without brakes, 
it just kinda worked out that way. We have the benefit of hindsight in 
designing D.
