//@ ### echo([options,] string [, string ...])

//@ + `-e`: interpret backslash escapes (default)
//@
//@ Examples:
//@
//@ ```javascript
//@ echo('hello world');
//@ var str = echo('hello world');
//@ ```
//@
//@ Prints string to stdout, and returns string with additional utility methods
//@ like `.to()`.
