You wrote "std::string does the same thing. So if I reimplemented 
subtex naively in C++, its performance would be closer to the C# 
version than to the D version."

"Naively" would mean that you didnt know better or that an 
alternative would be complex, but later on you acknowledged that 
doing it with slices would be better, but that you could not be 
bothered.  So you know better, but would rather choose to do it 
stupedly...

I have never said that you are stupid, what I said was the 
equivalent of  "std::string does the same thing. So if I 
reimplemented subtex stupidly in C++, its performance would be 
closer to the C# version than to the D version."

That line of reasoning is silly. I know that you know better, 
because you clearly stated so in the post I responded to.

Thats debatable...
