I am requesting that my library, the Variadic Macro Data library, which is in the sandbox in the variadic_macro_data directory, be reviewed for inclusion into Boost. The variadic_macro_data library adds support and functionality for variadic macros to Boost as well as integrating variadic macros with the Boost PP library without changing the latter library in any way. I believe others have used my library, can attest to its quality and that it does what it is supposed to do. and have found it useful when using variadic macros with Boost PP. I myself have used its functionality in my own TTI library in the sandbox. Support for variadic macros is implemented in nearly all modern C++ compilers and the syntax is natural for an end-user. The library is finalized as far as functionality is concerned and I would like to see it in Boost and am willing to maintain it as a Boost library. Edward Diener
