Subject: [boost] Lazy Spirit Generators?
From: Christof Donat (cd_at_[hidden])

In a hobby project, I am using Spirit Karma generators. As far as I have
understood Spirit Karma, it is not designed to work lazily in the
iterator based interface. It takes an output iterator and writes to it
until it has finished.

What I am thinking of is a kind of generating range. E.g.:

for(auto& char:
         generator_range(double_ << " + " << double_ << "i",
                         context, c.real(), c.imag())) {
    // do whatever with the single characters returned by the generator

Is there something like that, which I simply have not found?
