hi *

In the documentation for lambda library from boost_1_33_1, in section
"Getting Started"->"Conventions used in this document" said that in
all examples implicitly used such declarations:

using namespace std;
using namespace boost::lambda;

So the following will work:

for_each(a.begin(), a.end(), std::cout << _1 << ' ');

But how do I have to rewrite the above line of code to have it
compiled without "using namespace boost::lambda;" before it?

Thanks in advance.

This isn't really a boost question, but:
boost::lambda::for_each(a.begin, a.end(), std::cout<< _1 << '');

should work.
