Doing @WalterBright's job for a second to let you know that in the D language, given a function that is defined as taking, say, a list as the first argument, it can be called either

    myfun(list)

or

    list.myfun()

and this applies without exception. This means a lot of C-library code gets easier to read when used from D:

    Vector3 vec = (Vector3){ 1, 2, 3};
    Vector3 result = Vector3Add(vec, vec2);

becomes

    auto vec = Vector3(1, 2, 3);
    auto result = vec.Vector3Add(vec2);

I know its slightly off topic, but I want more people to use D, I really prefer it to C, C++ and Rust.
