// USAGE EXAMPLES:
//
// use std::regex
//
// fn main() {
//     // Simple matching
//     let re = regex.compile(r"\d{3}-\d{3}-\d{4}")?
//     
//     if re.is_match("Call me at 555-123-4567") {
//         println!("Found a phone number!")
//     }
//     
//     // Find matches
//     let text = "Emails: alice@example.com, bob@test.org"
//     let email_re = regex.compile(r"[\w.]+@[\w.]+")?
//     
//     for match in email_re.find_all(text) {
//         println!("Found: {}", match.text())
//     }
//     
//     // Capture groups
//     let date_re = regex.compile(r"(\d{4})-(\d{2})-(\d{2})")?
//     
//     match date_re.captures("Today is 2025-10-09") {

//         },
//         None => println!("No date found")
//     }
//     
//     // Named capture groups
//     let name_re = regex.compile(r"(?P<first>\w+) (?P<last>\w+)")?
//     
//     match name_re.captures("John Doe") {
//         Some(caps) => {
//             println!("First: {}", caps.name("first")?)
//             println!("Last: {}", caps.name("last")?)
//         },
//         None => println!("No name found")
//     }
//     
//     // Replace
//     let censored = re.replace("My number is 555-123-4567", "XXX-XXX-XXXX")
//     println!("{}", censored)
//     
//     // Replace all
//     let text = "Prices: $10, $20, $30"
//     let price_re = regex.compile(r"\$(\d+)")?
//     let result = price_re.replace_all(text, "€$1")
//     println!("{}", result)  // "Prices: €10, €20, €30"
//     
//     // Split
//     let parts = regex.split(r"\s+", "Split  by   whitespace")?
//     for part in parts {
//         println!("{}", part)
//     }
//     
//     // Quick one-off operations
//     if regex.is_match(r"^\d+$", "12345")? {
//         println!("All digits!")
//     }
//     
//     let result = regex.replace_all(r"\s+", "  too   much   space  ", " ")?
//     println!("{}", result)  // " too much space "
// }
//
// COMMON PATTERNS:
// - Email: r"[\w.+-]+@[\w.-]+"
// - Phone: r"\d{3}-\d{3}-\d{4}"
// - URL: r"https?://[\w./]+"
// - Date (YYYY-MM-DD): r"\d{4}-\d{2}-\d{2}"
// - IP Address: r"\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}"
// - Hex Color: r"#[0-9A-Fa-f]{6}"
//
// NOT THIS (regex crate exposed): ❌
// let re = regex::Regex::new(pattern)?
// let caps = re.captures(text)
//
// NOTE: regex crate is auto-added as dependency
