Also, C++0x static_assert is becoming available in more compilers; should all of the Boost compile-time asserts use C++0x static_assert if available?
Without knowing anything about how good the error messages are that one gets from static_assert, I'd say "probably."
Sample program: int main() { static_assert(1+1==3, "Everyone knows 1+1 == 4"); return 0; } Output from a beta compiler: temp3.cpp: Error E2538 temp3.cpp 3: Static assert failed: 'Everyone knows 1+1 == 4' in function main() *** 1 errors in Compile *** That's what I'd expect from most compilers; the file name and line number of the failure, and an echo of the second argument to static_assert. So it comes down to writing informative error messages. I like the ones that say both what is wrong and what to do to fix it, but that's often hard to do in limited space. --Beman
