Correct ... I want to do this for months now ... haven't find the time yet.

If someone wants to do it first, it would be great.
The basic idea is to use wave as the preprocessor and use waves output 
pragma to "unroll" the Preprocessor iterations. Once the initial step has 
been done, it should be quite easy for other libraries to adapt to this 
preprocessing technique.

The reason why I did not want to reuse the facilities developed for mpl is 
that the perl skript seems to be tailored just for mpl's use. IMHO, the 
effort to generalise this to enable preprocessing for other boost (or non 
boost) libraries is too high, compared to the effort of defining some wave 
specific macros.
