Actually I have LLVM embedded into a few projects, one is a noise
generator.  You literally just give it an iterator range and it spits
out a plain C function pointer, where the iterator range is to the
noise description data, and the plain C function pointer is an LLVM
generated version of the noise function very well optimized, so yes,
you can have C/C++ create code on demand as well, but as with
everything in C++ you have to import a library (and LLVM is not the
only one that can do this).  C++ does not follow the *everything* as
part of the runtime because libraries can do it all anyway, and there
can be many ways to do various things.  C++ can be extended to do
anything, *and* do it fast, unlike higher level languages.  As keeps
being used, look at Spirit, it creates a parser that runs faster then
anything else tested against it (it can even convert a string integer
to an int faster then atoi/strtol), and it is *very* high level.
