Hello, Boost::foreach is very useful for iterating over a sequence and doing something that depends only on the iterated element, e.g., <code> BOOST_FOREACH(const Foo &f, foos) cout << f.bar() << endl; </code> However, I often need to iterate over a sequence and do some operation that depends on both the iterated element and the iteration index. E.g., I would like something like <code> BOOST_FOREACH(size_t i, const Foo &f, foos) cout << "The bar of element " << i << " is " << f.bar() << endl; </code> Is there an easy way to do so? Thanks & Bye, TD
