If they joined for the wrong reasons, but D was initially 
"marketed" as a better C++, and only a small set of those early 
adopters are here still, so...

Anyway, integration with C by translating to the D AST is 
something I did strongly suggest years ago in these forums, so I 
am not complaining about the feature.

I only worry about existing ongoing efforts be significantly 
delayed. Like if refactoring the AST is desirable, then it better 
be done before this C-addition is merged in...
