// closure7.rs
// You can use patterns in closure (and function) parameters.
// However there is one big difference between the patterns
// you can use in these sorts of places (like let statements)
// and conditional places (like match). It's called Irrefutability.
// Make me compile!

// Execute `rustlings hint closures7` for hints!

// I AM NOT DONE
