This crate exposes the `ct-for!()` macro, which can be used to repeat code `n` times with a substitution.

For example:

```rust

let c = 17;

ct_for!(x in ["5", 6, c, vec![5, 6, 7]] do

    println!("{:?}", x);

);

```

expands to:

```rust

let c = 17;

println!("{:?}", "5");

println!("{:?}", 6);

println!("{:?}", c);

println!("{:?}", vec![5, 6, 7]);

```

The `ct_for!()` macro can also be nested.

There really isn't much more to it.
