Out of curiosity, have you considered at some point adding support for the new C++11 user-defined literals? I believe there would be a huge efficiency advantage in having the length of the literal at compile time, rather than having to determine it at run-time.
I don't know about other compilers but gcc can execute strlen in compile time if passed a literal as input.
Yes, but in real life I have only seen examples of such optimization when the code calls strlen inside a function and this function gets inlined. Then the compiler may be smart enough to see that strlen is actually called on a literal and replace it with a constant. I think I also saw this with some recent MSVC but I'm not sure. All in all, this optimization is at compiler's mercy.
