Binding and reordering function parameters

If you work with the standard library a lot and use the <algorithm> header, you definitely write a lot of functional objects. In C++14, you can use generic lambdas for that. In C++11, you only have non generic lambdas. In the earlier versions of the C++ standard, you can construct functional objects using adapter functions such as bind1st, bind2nd, ptr_fun, mem_fun, mem_fun_ref, or you can write them by hand (because adapter functions look scary). Here is some good news: Boost.Bind can be used instead of ugly adapter functions, and it provides a more human-readable syntax.
