...are you talking about extern "C" there? Because that's not at 
all how extern "C" works in a C++ compiler.

I mean, your point in relation to High Performance C# is valid, 
it's literally "C#, but everything that touches the garbage 
collector has been removed". And their rationale for doing HPC# 
was more to do with making sure engine logic and user-facing 
logic was written in the same language.

But it's also not really valid in relation to -betterC, which - 
as has been mentioned a few times in this thread - is more of a 
stand-in for "pay what you use of the D runtime" in lieu of DMD 
actually being able to do that. You don't need -betterC to @nogc 
and do completely manual memory management for example.
