You can mostly avoid macros now, thankfully. I'm particularly thinking of things like compile-time reflection, some more complex type introspection. Things that would let you get rid of some code generation like D's mixins perhaps.
Existing c++ reflection has mostly been done with macros, which you sacrifice readability for by declaring your class with macros instead, and I believe is often a runtime thing anyway.
Complex type metaprogramming is possible, sure, but often so obtuse and illegible I'd dare say the preprocessor is a better alternative if it works.
