Examples:
```rust use moreops::*;
// Simple wrapping into Option
let somenum = 123.some();
let nonenum = none::
// Simple wrapping into Result let ok = 123.ok(); let err = "Error!".to_owned().err();
// If-like operations with Option let x = 42; let answer = (x % 2 == 0).option("even").unwrap_or("odd");
// Tap into some result (like <| and |> operators from Scalaz)
fn f() -> i32 {
123
}
asserteq!(f().tap(|x| println!("{:?}", x)), 123);
asserteq!(f().then(|x| x * 2), 246);
// Swap result asserteq!(123.ok().swap(), 123.err()); asserteq!(123.ok().swap().swap(), 123.ok());
// Apply functions to tuples of args directly let x = (2, 3, 4).apply(|a, b, c| a * b * c); assert_eq!(x, 24);
// Use twice() to build map let map = (1..10).map(twice).collect::<::std::collections::BTreeMap<_, _>>(); ```
