I have written this code to return 2 to the power x.
Just a little confused reading your code; does POWER2(6) give you 64? Or 
are
you trying to produce the sequence 1,2,4,8,16,32,64? If the former, why 
not
simply use the left shift operator?

I can't find this left shift operator in Boost.PP.
Do you mean   <<  ?
But then how do I evaluate it in the context of the preprocessor?
