I have been trying to prevent variable substitution with boost::lambda and cannot figure out how to prevent variable substitution.

Here is a (simplified) version:
double first_moment(double x)
{
    return x;
}

//And create a function
auto myfunc = first_moment(_1);
cout << myfunc(2.0);

... This doesn't compile, and every permutation I can think of using protect, etc. fails as well.

Now I realize that this looks like a job for "bind" (which works fine of course) but this is a simplified pattern of the notation I want.  Is there any way to do this with protect, unlambda, etc. around the _1?

Are other libraries like Phoenix a better place to look for this kind of functionality?  Do people see Phoenix as the evolution of boost lambda or are these likely to remain in parallel?  Should I stick with C++0X lambdas?

Thanks,
Jesse
