using boost foreach with items that are themselves templates
boost, boost-foreach, c++
Solution
As the author of `BOOST_FOREACH`, I ask you to please stop using it. It was a hack whose time has come and gone. Please, please, please use C++11's range-base for loops and let `BOOST_FOREACH` die.
Problem
I have a `std::deque< std::pair<int, int> >` that I would like to iterate over using `BOOST_FOREACH`. I tried the following: ``` #define foreach_ BOOST_FOREACH // declaration of the std::deque std::deque< std::pair<int, int> > chosen; foreach_( std::pair<int,int> p, chosen ) { ... } ``` But when I compile this (in Visual Studio ) I get the following errors: ``` warning C4002: too many actual parameters for macro 'BOOST_FOREACH' 1>c:\users\beeband\tests.cpp(133): error C2143: syntax error : missing ')' before '>' 1>c:\users\beeband\tests.cpp(133): error C2059: syntax error : '>' 1>c:\users\beeband\tests.cpp(133): error C2059: syntax error : ')' 1>c:\users\beeband\tests.cpp(133): error C2143: syntax error : missing ';' before '{' 1>c:\users\beeband\tests.cpp(133): error C2181: illegal else without matching if ``` What is the correct way to use `BOOST_FOREACH` with this `deque`?
