// In boost, the placeholders _1, _2, ... are in the global namespace. In
26
// C++11, they are in namespace std::placeholders, which makes them awkward to
27
// use. Import them into the ::std_cxx11 namespace instead and do the
28
// same below if we use boost instead. Namespace 'placeholders' is also defined
29
// in ::std_cxx11 namespace to make code C++ standard compatible.
30
// That is to say, if std::something works with C++11 standard,
31
// then ::std_cxx11::something should also work.
