People in the D community has the wrong understanding of what 
"undefined behaviour" means in a standard specification… this is 
getting tiresome, but to state the obvious: it does not mean that 
the compiler cannot provide guarantees. The fact that C++ choose 
performance over other options does not make this a necessity. It 
is a choice, not a consequence.
