Hi Joel,

Oops, that should be

typedef mpl::vector_c consts_type; typedef fusion::vector vars_type;

vars_type vars; fusion::joint_view s3(consts_type(), vars);

Anyway, I'm sure you got the point. With our 's3' above, we can, for exemple, write (using boost::lambda):

fusion::for_each(s3, cout << _1 << endl);

to print all the items.

I just tried your suggestion and it works until the fusion::for_each() call. There, I get a million compiler errors. I'm sure I'm must missing something simple here.

This is what I'm doing:

[snip code] My mistake. The code should be: typedef mpl::vector_c consts_type; typedef fusion::vector vars_type; consts_type consts; vars_type vars; fusion::joint_view view(consts, vars); fusion::for_each( view, cout << _1 << "\n" ); (Sometimes I can't figure out various aspects of lambda. Here, it can't grok std::endl. Anyway, that's an unrelated issue. You can simply throw in your function/function-object there.)

When I got the CVS head there was no fusion documentation included. Is that correct?

It's there now. Regards, -- Joel de Guzman http://www.boost-consulting.com http://spirit.sf.net
