Re: [Boost-users] [Proto] Storing an Expression Template as a Data Member

      2011/1/7, Hossein Haeri :
...
MyClass mc(_1 >> &f >> &g >> &h);
mc.set_input(-61.1);
cout << mc.value();//returns h(g(f(-61.1)))
Now, are you telling me that I can store that "_1 >> &f >> &g >> &h" bit in
a data member of mc using make_expr? If so, what will the type of that data
member be? Or, are you suggesting a totally different design?
Hi, Hossein. IIUC, you may need some way to abstract the ET away,
maybe by using boost::function, like what Spirit does for its rule
component.

Is this what you want?
