I should have mentioned as an aside what I did in FC++ for input/output; I made functoids in_stream and out_stream which take pointers to streams as the lhs: &cout ^out_stream^ x ^out_stream^ y ^out_stream^ z; // cout << x << y << z; This is one way to "functoidize" such operations. It's unclear to me if/how useful this is. A question I should I asked before: why were you using FC++ in the first place? (That sounds too accusatory. :) ) What feature(s) motivated its use? Can you give an example of a "linear algebra pipeline" that you might want to express as a functoid (or something)? I'm afraid I don't have a good enough sense of the domain and what FC++ features you wanted; there may be some useful solution along a completely different path... -- -Brian McNamara ([EMAIL PROTECTED]) _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
