Module io 

I/O Operations for LOGOS Programs

Provides input/output primitives for LOGOS programs including:

• show: Natural formatting output (primitives without quotes, collections with brackets)
• print, println, eprintln: Standard output functions
• read_line: Read a line from stdin

The Showable trait enables custom types to integrate with the show verb.

Example

use logicaffeine_system::io::{show, println, read_line};

// Natural formatting with show
show(&42);           // Prints: 42
show(&"hello");      // Prints: hello (no quotes)
show(&vec![1, 2, 3]); // Prints: [1, 2, 3]

// Standard output
println("Enter your name:");
let name = read_line();
println(format!("Hello, {}!", name));
