### Lazy Statements

Lazy statements? Sure. There are lazy versions of the C++ statements we all know and love. For example:

    if_(arg1 > 5)
    [
        std::cout << arg1
    ]

Say, for example, we wish to print all the elements that are greater than 5 (separated by a comma) in a vector. Here's how we write it:

    std::for_each(v.begin(), v.end(),
        if_(arg1 > 5)
        [
            std::cout << arg1 << ", "
        ]
    );

(See if.cpp)
