Data Objects

Overview 

Sometimes, a fully-defined class is overkill, and all you need is a way to attach some methods to a piece of data (i.e. a Map).

Bound Methods 

When you assign an anonymous function to a Map key, any reference to @ inside the function will automatically be bound to the Map.

This lets you create dynamic objects on the fly, much like JavaScript’s object literals.

$user = {
    name: 'Tadala'
    job: 'Teacher'
    about: fun {
        return @.name ~ ' works as a ' ~ @.job
    }
}

$user.about()
//= 'Tadala works as a Teacher'
