Thanks for the info. Useful, makes sen= se, the only thing I still wonder:

- Why the D pro= gramming language does this non-intrusively? It is fair to ask that I guess= , because for them it is working.
Do they have the same potential= problems as described in this thread? 

See this 2007 thread: http://goo.gl/a7P4CK an= d look for postings by Walter Bright. IIRC, one difference is that D does n= ot do dynamic initializations of static variables, and that somehow removes= the need for a separate constexpr keyword.
