Is there any specific reason for not having std::copy_if algorithm in C++ ? I know I can use std::remove_copy_if to achieve the required behavior. I think it is coming in C++0x, but a simple copy_if which takes a range, a output iterator and a functor would have been nice. Was it just simply missed out or is there some other reason behind it?

根据 Stroustrup 的C++ 编程语言"，这只是一个疏忽.
According to Stroustrup's "The C++ Programming Language" it was just an over-sight.
