Note that I'm not a GCC developer, so my opinion isn't worth much on the acceptability-to-GCC front. Wouldn't this make it a C++ dialect? How would non-GCC compilers be able to be compatible with such an API? That is, if the schema and query being available changes the API (nevermind the schema itself changing), I don't see how this works in general. --Ben
