I don't know what you definition of "code generator" is, but I think, it's
what allows to generate code based on some minimal input provided. So, if
my user says:
And this is expanded into two template specializations for class template
foo, with a class, bool, and template<class, class> class template
parameters, one of them capable of serializing an instantiation of such a
template into a compile-time vector of integral constants, and another one
capable of re-constructing such an instance from this vector, you would not
qualify it as "code generation"?

Preprocessor has an obvious advantage of availability to everybody. I, for
instance, am very reluctant in downloading/using tools. I suspect many
people are like this, too.
"Don't repeat yourself". Many tasks would require manual code duplication
if not done with Boost PP (which does it for you)
