It should be possible to implement extern(C++) using ctfe/string mixins, 
as all that needs doing is the name mangling. This is something tools 
does, allowing you to have the equivalent in D1 [1].

Add to this C++ name mangling doesn't work a lot of the time on 
linux[2]. I think it's definitely possible to replace it with something 
in std, possibly based on the code from tools. If it's dropped it does 
mean a chunk of ddmd will need rewriting, I don't see this as too much 
of an issue though.
