9742,for_each causes funny behavior in phoenix V3 expressions,Chromatix,Thomas Heller,"Using phoenix::for_each in a Phoenix expression produces a strange behavior, which seems to be reverse execution of the comma-separated expressions.
This does NOT happen when you include Phoenix V2 from the spirit directory.

Sample Code: (Full code attached)


{{{
std::vector<int> v{1,2};
(std::cout << phx::val(""(""),  phx::for_each(arg1, phx::lambda[std::cout << arg1]), std::cout << phx::val("")""))(v);
}}}


This originally showed up for me when using phoenix expressions in spirit semantic actions, discussed here:
