How about this?
// Must expand to "int foo8;", but it does not. int BOOST_PP_CAT(foo, POWER2(3));
Roman Perepelitsa.
Exactly. Ravi, the macro expansion does not evaluate the << operator, that is done at compile-time. So Roman, what do you think of my POWER2 implementation? It is very slow (to preprocess) in an actual example I have. Can anyone see a faster implementation? Regards,
