...while understanding all the consequences of the PP design is obviously not necessary for basic PP metaprogramming, I think that it is almost impossible to be able to use the PP (and the Boost.PP library) profitably (beoyond trivial use of macros like ENUM_PARAMS and REPEAT) without having a fairly good understanding of the capabilities and limitations of the PP.
I think I got a lot of useful work done with the PP lib with only a fairly poor understanding, and once I had done that, it was a lot easier to improve my understanding from fairly poor to moderately good. Actually, the process of getting useful work done in itself did a lot to deepen my understanding. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
