Usage

```rust use expand::expand;

// expanding a byte string assert_eq!( &expand!([@b"Hello,", b' ', @b"world", b'!']), b"Hello, world!" );

// expanding a string assert_eq!( expand!(vec![@"Hello,", ' ', @"world", '!']), "Hello, world!".chars().collect::>(), );

// pattern matching if let expand!([@b"patt", x, y, b'n', ..]) = b"pattern matching" { asserteq!(x, &b'e'); asserteq!(y, &b'r'); } else { panic!("pattern matching failed"); }

// more pattern matching if let expand!([@b"msg = \"", xs @ .., b'"']) = br#"msg = "Hello, world!""# { assert_eq!(xs, b"Hello, world!"); } else { panic!("pattern matching failed"); } ```
