Re: [boost] [fusion] constructing all elements of the fusion vector with the same argument

If we have a /lazy-sequence/ s, that generates the ones for you, then you can use that for s:

vector<int, float, double> ones(all_ones);

all_ones is a lazy-sequence. It generates the ones every time the iterator is dereferenced.

A nice strategy is to write a function adaptor that creates a fusion sequence. Example:

int one() {return 1}

...

vector<int, float, double> ones(fusion::make_lazy_sequence(&one));

How about hacking on the /lazy_sequence/ idea? Thoughts?

I *love it*. Attached is something... similar ;-) (I used the triple.cpp example as a starting point, it was pretty straightforward) What do you think? Stjepan
