//! Control flow related macros
//!
//! Many times one would like to return from a function or continue iterating if an `Option` or
//! `Result` was not valid. These are some simple macros to facilitate that.
//! 
//! ```rust
//! use pino_utils::ok_or_continue;
//! 
//! fn main() {
//!     
//!     for str in vec!["1", "one", "2", "two"] {
//! 	     let num = ok_or_continue!(str.parse::<u32>());
//!     }
//! 
//! }
//! ```
