1/// Sugar macro similar to Python's `input()`.
2///
3/// Usage:
4/// ```ignore
5/// let name: String = input!("Name: ");
6/// let tries: u8 = input!("Retries (default 3): ", default = 3);
7/// let port: u16 = input!("Port: ", retries = 2);
8/// let pct: f32 = input!("Percent [50.0]: ", default = 50.0, retries = 3);
9/// ```
