See this 2007= thread: http://goo.gl/a7P4CK and look for pos= tings by Walter Bright. IIRC, one difference is that D does not do dynamic = initializations of static variables, and that somehow removes the need for = a separate constexpr keyword.

Thanks, that replies my last question.


:(((( I want that feature, it would enable, essentially, that I ca= n embed interpreters in metaprograms reusing the code written by others. Th= e alternatives are: 

1. modify source from ot= hers. 
2. rewrite interpreter :(

I = have the intention of integrating in a toolchain some way of compile-time i= nterpretation, this way I can have the benefits of runtime development, dyn= amically, like live coding. When done: just put that into the source direct= ly, compile to make it work really fast. So I would have the best of both w= orlds.
